Rachel Zoe's adorable son turned three over the weekend, and the proud mama shared some sweet snapshots on Instagram from his birthday bash.

"Celebrating my love and my heart my angel Skyler Morrison's 3rd Birthday..#Happybirthday #livinginstyle #NYC #familyweekend," she wrote, along with the snapshot of Sky admiring a cake topped with a giant sparkler.


"Most magical family day celebrating my Skyler Morrisons 3rd birthday xoRZ #family weekend #livinginstyle #NYC," the celebrity stylist captioned a collage that included a another pic of her little one blowing out candles.

Another photo showed the 42-year-old fashion maven snuggling with her newborn baby boy Kaius, who was born in December. She also was captured getting cozy with her hubby Rodger Berman.

A third photo caught Zoe happily holding Kaius, while posing with good friends Brian Atwood, Joey Maalouf and Dr. Jake Deutsch.

What a cute family!
