Lively posted a sweet Instagram photo on Thursday, in which she cradles the pregnant star’s growing baby bump. Tamblyn looks radiant in red, holding Lively’s hand on her belly and opening her mouth in excitement. The mom-of-two couldn’t look happier for her friend, resting her head on her shoulder. “’I am asking you to rethink women, period. Go deep. See the frame that holds the big picture…’ So proud of my dear friend, and new mama to be, @amberrosetamblyn,” Lively wrote. “Whatever your beliefs, one thing is certain, the world must be a better, safer place for women and girls. The time is now.” VIDEO: Blake Lively's Maternity Style Is Seriously on Point The Shallows star knows a thing or two about motherhood: She welcomed her first child with hubby Ryan Reynolds back in December 2014, a baby girl named James, and delivered a second child in September.
