They're not shy about showing off the goods on social media!

Bella Hadid and Kendall Jenner both posted sexy selfies on Instagram yesterday, and while they looked hot, people are wondering if Kenny might have doctored hers up with a little Photoshop.

Kimmy K's little sis shared a close-up pic of her butt, but her fans think she altered it to make her booty appear more round. One person with intimate knowledge about the real size of her bum? Boyfriend Blake Griffin!

The supermodel and the Clippers star's romance is going strong, but she's hesitant to commit to being in an exclusive relationship.

“He is super into her. She thinks he’s dorky and funny, but also cool and sexy. She thinks he has a certain attractive ‘swagger.’ They are seeing each other more and Blake is doing everything in his power to make Kendall his girlfriend, but she is keeping him at arm’s length because she knows how busy she is," a source dished to People.

"She’s always working and traveling and knows a full-blown relationship isn’t necessarily the best idea, but things are heating up and she is for sure enjoying dating him,” the source added.

As for Bella, it seems like this snapshot might have been for new beau Drake!
