Khloé Kardashian is proving she’s not “Heartless” when it comes to her estranged brother-in-law, Kanye West.

The youngest Kardashian sister wore the rapper’s “Saint Pablo” sweatshirt while taking daughter True to gymnastics class Friday.

She paired her hoodie with black leggings and Ugg Classic Tall II boots ($200), while her 3-year-old wore a tie-dyed leotard and braids.

It’s possible it was simply laundry day for Khloé, 37, but she could also be showing support for Ye despite his ongoing issues with her sister Kim, with whom he’s in the midst of a bitter divorce.

The interesting style choice comes only days after West, 44, released a music video attacking Kim’s new beau, comedian Pete Davidson. In the “Eazy” clip, Ye kidnaps a Claymation version of the “SNL” star and buries him alive.

The “Monster” rapper justified the cartoon violence by captioning an Instagram clip of the vid with, “Art is therapy just like this view. Art is protected as freedom of speech.”

Coincidentally, West grabbed dinner in Miami last week with Khloé’s ex (and True’s father), Tristan Thompson.

Recently, Ye has been spotted with model Chaney Jones, who looks remarkably like Kim. They’ve been romantically linked since late February, following the rap superstar’s split with “Uncut Gems” actress Julia Fox.

Now that all of the Kardashian exes are spending time together, perhaps we’ll see Kim and Julia join forces next; they already share similar senses of style, so a shopping date could be in order.
