Baby Kaius is ready for his close up! 

Rachel Zoe posted the most adorable picture of her newborn baby boy, Kaius Jagger, on Tuesday via Twitter

"Kaius' first trip to the office ... he loved meeting Team Zoe obvi #angel," the stylist captioned the sweet snap.

The "Rachel Zoe Project" star announced the birth of Kaius on Twitter back in December, and this is the first time we've seen a close up of her little bundle of joy.

This the the second child for the 42-year-old and her husband Roger Berman -- who've been married since 1996, and are parents to son Skyler, 2. 

Even though Zoe is outnumbered in the house, it doesn't seem like she minds having three special guys in her life! 

"Feel so lucky to have 3 Valentines forever my loves @rbermanus and my angels #skylermorrison #kaiusjagger," she posted on Valentine's Day.
