Los Angeles: Actress Blake Lively`s behaviour on the set of ‘Gossip Girl’ has fuelled rumours she might be pregnant with her first child with Ryan Reynolds.

A source on the ‘Gossip Girl’ set reveals Lively has been practically "glowing" and "indulging in more food than usual" since filming commenced, reports

"Blake is usually really careful about what she eats, but since her wedding, she seems to be eating a lot more. Everyone on set is on bump-watch," said the source.

Lively and Reynolds have not responded to the pregnancy rumour.

The couple married earlier this month at Boone Hall Plantation at Mount Pleasant, near Charleston in South Carolina, in front of family and friends, including Florence Welch.

They started dating October last year, after the actor`s divorce from Scarlett Johansson was finalised. They also starred together in the superhero epic `Green Lantern` last year.
