Former CAA agent Brewster and Baron married back in February, five months after Us confirmed their engagement. The couple celebrated with Jessica Alba and her husband Cash Warren and Brewster's older sister, Fast & Furious star Jordana Brewster.

Brewster and Barron announced they were expanding their family on April 13. "AAYYEE AAYYEE Happy Birthday to my Love, Husband and Baby Daddy," Brewster wrote via Instagram on Baron's 35th birthday. "Love You!"

The couple's little one already has a playmate, too. Jordana welcomed son Julian with husband Andrew Form last September.
