Reynolds, Lively at war over children?

Actor Ryan Reynolds and his wife Blake Lively are apparently fighting over children.

"He's 37, but she's only 26. She says she's too young and not ready for that step," showbizspy.com quoted a source as saying.

The duo was married Sep 9, 2012 at Boone Hall Plantation, Mount Pleasant, South Carolina.

Reynolds was earlier married to actress Scarlett Johansson.

Lively met Reynolds during the filming of "Green Lantern" in 2010.

Sources said that "The Proposal" star is a possessive husband and apparently follows Blake everywhere she goes. He flies from Vancouver, Canada quite often and visits the actress on the set of her new movie "The Age of Adaline".

"He's very possessive of Blake. She's been doing night shoots, and Ryan keeps showing up, which infuriates her. He appears to be worried about her relationship with co-star Michiel Huisman."
