Just a little birthday love! Scott Disick and Sofia Richie are still going strong nearly one year after they started dating, and Sofia shared a sweet Instagram photo wishing her man a happy birthday on Saturday, May 26 and Lionel Richie's youngest daughter even professed her love for Scott in the caption.

"Happy birthday babe! Thank you for being you. Love you," the 19-year-old wrote in a sexy photo of them cuddled up in the ocean as Sofia wore a tiny black bikini.

The couple is currently in St. Barth's for a vacation to celebrate Scott's birthday, and it also seems like Scott's children — he shares eight-year-old son Mason, five-year-old Penelope, and three-year-old Reign with his ex-girlfriend Kourtney Kardashian — are with them on vacation.

In one snap on his Instagram story, little Penelope posed with a little artwork that she created for her father — stones spelling out the word "dad" with flowers and palm leaves around it. Scott also shared a photo on his feed of him with his youngest son Reign sharing a sweet kiss on the lips. "Me and mini me," he wrote in the caption.

It seems like Scott is having a blast celebrating his 35th birthday with his kids and his girlfriend, and since the father-of-three loves being a dad, it's makes sense that he would want to have more children with his current girlfriend. Sources exclusively revealed to Life & Style that Scott wants to make Sofia his baby mama No. 2.

"Scott is putting pressure on Sofia to have a baby. He’s crazy about her," an insider told Life & Style. But Scott's motives might not be completely pure. "He loves living a lavish lifestyle, and pushing Sofia to have a baby is a way into her wealthy family. He’s concerned he’ll gradually be forgotten, which will mean less endorsement money. He’ll do whatever it takes to continue living the lifestyle he’s become accustomed to."
