Paris's little bro, Barron Hilton was on set with his model girlfriend Vanessa Dubasso.
They were doing a photo shoot on a boat and he brought along his adorbz bulldoggy!
She's pretty but we think that dog is the cutest!!
We're glad Barron brought him along, we hope they're best friends because we'd be friends with that doggy!
