Kristin Cavallari and Jay Cutler could not have looked any more in love during their recent trip to Mexico. The couple, who jetted off to Punta Mita for Kristin's 30th birthday earlier this week, drank out of coconuts, lounged by the pool, and enjoyed a relaxing boat ride. The former The Hills star gushed over her fun getaway alongside an Instagram photo of her and her husband on Monday, writing, "I had the best birthday of my life and it was all thanks to this guy. Not only did he plan a huge surprise party, he planned a 'surprise' trip to Mexico with some of my closest friends, too. Thanks, babe." It's unclear whether their kids, Saylor, Jaxon, and Camden, joined them, but we often catch glimpses of them on social media.
