Anne Hathaway pregnant? Actress' brother reveals 'baby bump' secret in 'Uncle Tom' joke, husband Adam Shulman 'extremely giddy'

Last winter, rumors began swirling online that "Les Miserables" actress Anne Hathaway was pregnant with her first child. The 30-year-old Hollywood beauty quickly denied such baby bump claims:

But now, Star magazine insists that Hathaway is indeed expecting a baby with hubby Adam Shulman. Apparently, Hathaway's own brother Tom revealed the couple's little "secret." According to an alleged insider, Tom "let the supposed news slip" while performing a standup comedy routine at Brooklyn's Tandem Bar and Restaurant on October 30.

An eyewitness audience member tells the popular gossip mag, "Tom opened his act by talking about Anne's personal life... He said, 'My sister got married last year, and now she's about to be a new mom!' I don't think he realized what he had done."

Another supposed source reveals, "Anne is over the moon, and Adam is extremely giddy."

How exciting! If only the rumors were true...

Gossip Cop talked to Hathaway's rep, who insists that “she is not pregnant.” Hathaway's brother was just joking about how “one day his sister would be pregnant and then he would be Uncle Tom.”

Apparently, Star magazine threw this "ha ha" moment completely out of proportion.

Hathaway and Shulman tied the knot in September 2012. Hathaway once admitted that she'd like to have children one day, just not yet.
