Reese Witherspoon, who turns 36 tomorrow on March 22, is expecting a child with her new husband, Jim Toth, 41, the head of motion picture talent at Creative Artists Agency. The two were married almost exactly a year ago. This will be the third child for Reese, who has a daughter, Ava, 12, and son Deacon, 8, from her first marriage to Ryan Phillippe, and the first child for Toth. A source confirmed to Us Weekly that Reese is about 12 weeks pregnant but she is “not planning to announce it.” She was spotted on vacation with her children and husband in Rio de Janeiro recently, sporting a slight baby bump. “The timing is right,” the source said. “She’s so happy!” Reese can currently be seen on the big screen in the comedy This Means War.
