She and husband Brian Austin Green welcomed their third child in August
The actress shared a mother-son selfie on Instagram Wednesday, marking the first time she’s posted a photo of her 3-month-old baby boy on social media. Fox, 30, and husband Brian Austin Green welcomed their third child together in Los Angeles in August.
Fox made her surprising pregnancy announcement in April when she stepped out at CinemaCon in Las Vegas to promote her film Teenage Mutant Ninja Turtles: Out of the Shadows, sporting a visible baby bump.
The parents of three, who’ve been married since 2010 and together for a total of over 10 years, recently reconciled after Fox filed for divorce in 2015.
