Sofia Richie shared on Instagram this weekend a birthday message for her boyfriend, Scott Disick.

"Happy Birthday babe! Thank you for being you. Love you," the 19-year-old daughter of Lionel Richie captioned a photo of her embracing 35-year-old Disick in the ocean.

Disick also posted on social media a snapshot of him kissing 5-year-old Penelope, his daughter with his ex-girlfriend Kourtney Kardashian.

"Me and mini me," the "Keeping Up with the Kardashians" star wrote.

His sons Mason, 8, and Reign, 3, also helped him celebrate his birthday while they were all on vacation.
