Rumors have been circulating around the Gossip Girl set that newlywed Blake Lively is expecting her first child with husband Ryan Reynolds, but her rep is shooting down the reports as completely false.

Apparently, the 25-year-old star has been "glowing" and relaxing her strict diet since her Sept. 9 nuptials to her Green Lantern co-star, leading sources to believe her secret quickie wedding was because she is pregnant.

"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 source dished to the NY Post.

We all know women wait until the three month mark to announce a pregnancy, and even though her rep denies the baby rumors, we will remain on bump watch! If the blonde actress really is pregnant, that's going to be one good looking baby!
