Do you wear the trousers in your relationship or do you tend to let your partner lead the way? If you’re unsure there’s now a very simple way to find out. 

Called the ‘Green Line Test’, it has been doing the rounds online. TikTok has hundreds of thousands of videos about it, racking up 11.2 billion views this week.

So does it really stand up to scrutiny? Yes, says body language expert Mike Carter: ‘We tend to lean physically towards things that we want, like and feel strongly about.’ 

So, should we all be leaning towards our partners? Rachel New, a relationship coach, says leaning indicates a person is willing to ‘accept influence’, which means they take on board their other half’s suggestions and are open to changing their mind without becoming defensive. 

‘Men tend to be less good at this, so if the man is leaning in it is a very good sign that he feels secure and confident in himself,’ she adds. ‘Ideally both partners would lean in, but the man leaning in is a close second for a healthy relationship.’ 

We picked out celebrity couples – looking at dozens of photos of each to find their typical posing style – and put them to the Green Line test…

HARRY AND MEGHAN

Dominant: Meghan 

Having moved across the Atlantic to raise his family, it comes as no surprise that it is Harry, 37, who leans towards Meghan, 40, in the majority of photographs. In their official engagement portraits, wedding photographs, and during last year’s bombshell interview with Oprah Winfrey; each time Harry is leaning in to an unbending Meghan. 

‘He’s moving in towards her, and the hand position is revealing, too. Her hand is on top of his, and her shoulder is in front of his body, both of which suggest control,’ says Mike.

BEYONCE AND JAY-Z 

Dominant: Jay-Z 

Power couple Beyoncé, 40, and Jay-Z, 52, have been together for over 20 years and it seems their relationship — which survived a year-long breakup and three children — is on a pretty even footing. 

Beyoncé may be more of a household name; she’s sold 118million records and is worth £397million. However, photographs tell a different story. Beyoncé — who once said of her beau: I love him so much we almost feel like one’ — is the one with the diagonal line, leaning towards Jay-Z. 

‘She is leaning in and he is holding her, with his arm on top of her to reinforce the balance of power,’ says Mike.

BEN AFFLECK AND JENNIFER LOPEZ 

Dominant: Neither 

Actor Ben, 49, and singer J-Lo, 52, have had a rocky relationship, to say the least. The pair were engaged from 2002 to 2004, avoided each other for 17 years – and then rekindled their friendship before getting back together last June. 

Perhaps because of their history, or the fact that they’re still in the honeymoon period, there are not one but two diagonal lines in their recent pictures, with both leaning lovingly towards one another. 

‘This is an affectionate photograph,’ says Mike. ‘Their bodies are reasonably straight but the angle of the head is important. A straight head is confrontational, but putting your head on an angle is more sympathetic and appeasing.’

WILL SMITH AND JADA PINKETT-SMITH 

Dominant: Jada 

His Oscars outburst might give a clue to the dynamic in this relationship, and pictures display a clear pattern of Will leaning in. 

Will, 53, and Jada, 50, have a notoriously complicated relationship: there were rumours of an ‘open marriage’ in 2013, they quietly separated in 2016 and by 2018 were back together with Will calling Jada his ‘life partner’. 

This complexity is reflected in their photographs, Mike says. 

‘While he’s leaning towards her, the angle of his head is quite straight and almost pointing away from her — this suggests he may be being controlled by her. ‘But he also has his arm around her, and this shows he’s protecting her, too. So although he’s leaning in, he is “steering” her from behind. A complex relationship.’ 

DAVID AND VICTORIA BECKHAM 

Dominant: Victoria 

Possibly the best-known celebrity couple in the world, David, 46, and Victoria, 48, have been photographed together tens of thousands of times during their nearly-23-year marriage. Almost every single picture of the pair — who have a joint net worth of £355million — clearly reveals the balance of power, following the Green Line theory. While David dutifully leans in towards his wife, Victoria is pictured leaning away. 

‘She’s almost moving backwards,’ says Mike. ‘She is pushing herself up against him in a pose that clearly says: “I’m a sexy woman and this is my man.”’ 

David, meanwhile, has a hand behind his back; body language that bolsters Victoria’s dominance. 

KATE AND WILLIAM 

Dominant: Neither 

Poised and picture-perfect, the Cambridges’ photographs are very staged, whether official press shots or more intimate family snaps taken by Kate. 

The lines are very straight, illustrating an equal, shared dynamic. Here, on their 2016 tour to India and Bhutan, both William, 39, and Kate, 40, are straight-backed with only their heads nodding in towards one another. 

‘He always has his head on one side; this is non-confrontational body language,’ says Mike. ‘And they both have their hands on view, a classic sign of credibility. 

ELTON JOHN AND DAVID FURNISH 

Dominant: Elton 

Singer Elton John, 75, who’s sold 300million records over six decades, may dwarf his filmmaker husband David Furnish, 59, in career terms, but pictures suggest things aren’t quite as clear-cut when it comes to their marriage. 

Pictured with his Oscar for best song from the 2019 film Rocketman, Elton is sitting straightbacked while David leans in towards him. 

However, adds Mike, ‘David is grasping the Oscar even though he didn’t win it. Elton has handed it over, letting David hold it and then putting his hand around David’s. It shows he may be slightly dominant, but it’s also hugely affectionate.’ 

GEORGE AND AMAL CLOONEY 

Dominant: George 

The notoriously private couple, who married in 2014 and have fiveyear-old twins let very little slip about their relationship — and aren’t often pictured in public. 

However, in a rare, recent interview, human rights lawyer Amal, 44, described Hollywood star George, 60, as her ‘great love’. 

‘She’s definitely moving towards him,’ says Mike. ‘She is wanting to be protected. But she’s also cuddling up to him — it’s not simply about dominance. 

‘In fact, the arrangement of the interlocking hands is interesting. Her hand is slightly on top of his, so she’s saying it’s not always him who’s in charge.’ 

BORIS AND CARRIE JOHNSON 

Dominant: Neither 

Carrie Johnson, 34, might have a reputation for keeping the PM on his toes, but photographs suggest their relationship dynamic is on a much more even keel. 

While Boris, 57, who has had two previous marriages and fathered seven children, may come across as bumbling and inept, pictures suggest he is more than capable of keeping up with his younger wife. ‘There’s a real symmetry to the way they’re walking in this photograph,’ says Mike. ‘They’re in sync with one another, which suggests there’s synchronicity in their relationship. 

‘Boris always hides his hands; here, one is behind his back, and that’s not a good sign as it suggests untrustworthiness.’
