Catherine Zeta-Jones paid tribute to eldest child Dylan Douglas on Monday while watching him graduate from Rhode Island‘s prestigious Brown University. 

The Welsh actress was in attendance as Dylan, 21 – the first of her two children with Hollywood star Michael Douglas – collected his degree certificate after majoring in political science. 

Taking to Instagram following the ceremony, Catherine, 52, shared a photo of her son dressed in traditional mortar and gown as he accepted a kiss from his proud mother.

Brown, a private Ivy League research university, has previously been attended by celebrities including Tracee Ellis Ross, Laura Linney, John Krasinski and Harry Potter star Emma Watson. 

Last year Catherine took to Instagram to share a photo of her and Dylan after she paid him a visit at his college campus.

The two smiled at the camera as she kept a low-profile in a pair of round sunglasses and a scarf while she took a selfie with her son.
