Not pregnant....just a little overweightKatie has denied rumors that she and new husband Tom Cruise are expecting a second baby.

Katie sparked rumors of her second pregnancy thanks to a fuller figure during the post-wedding party thrown by Tom's production partner Paula Wagner.

A source at TomKat's recent post-wedding party in L.A told that the actress' reported pregnancy was the main topic of conversation.

"You could hear everyone whispering the same question to each other - is Kate pregnant again?"

The insider also revealed that quite a few women at the party were sure that Holmes was expecting her second child, for she had a "special glow about her."

"She had that special glow about her. Some women in the room were certain that she's expecting," new magazine articles said.

However, Katie's representative dismissed the pregnancy claims by stating that she is not expecting.

"To our knowledge, Katie is not pregnant." Maybe this will give Katie some incentive to pick up pilates or yoga, maybe even go on a low calorie diet.
