Rumors are rife on the “Gossip Girl” set that Blake Lively could be expecting her first child. The blond beauty, back at work in New York after her secret Sept. 9 wedding to Ryan Reynolds, is “glowing,” say spies, but also is eating more than normal.

One spy said, “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.” A rep for Blake didn’t respond to e-mails last night.

UPDATE: Blake’s camp responded to the report this morning telling Page Six she is not pregnant.
