Yes, he is officially off the market!

The photo shows Kaitlynn in a bikini with her hand cupping Brody's face as he happily smiles. The couple have also been joined on their holiday is Brody's mum Linda Thompson and Kaitlynn's parents.
Speaking to us last year, Brody, who is the son of Caitlyn Jenner and the step-brother of Kim Kardashian, revealed that he would love to start his own family.
"Yeah, one day I'd love to have a family of my own but I feel like I have a lot more stuff to do and accomplish. I would like to do that first and when that happens and I feel like I'm in a more stable place in my life, when I'm not travelling so much with the DJ-ing as I am at the moment and stuff, then yes. I've been extremely busy and when I become a dad, I want to devote 100 percent of my time to that.
"I know I'm going to be a protective dad. Especially if it's a little girl, because I know what's going on out in the real world here. Other than that, I want to be a friend to my child and make sure they see me as a friend and not just a parent."
