We've heard this a million times, but it sounds like there's finally some truth to it!

Jennifer Aniston is reportedly pregnant with fiancé Justin Theroux's child at age 44, Us Weekly reports.

The A-list actress is on the cover of this week's issue of the mag with the headline "Jen's Big Secret. Pregnant!", and although the star's rep vehemently denies the reports, the glossy provides proof of their claims.

Mainly, that the former Friends star has been going to great lengths to hide her growing baby bump while she promotes her two films We're The Millers and Life of Crime.

"Her stylist had to redo her whole press tour wardrobe," a source dished to the publication.

Us also cites a Smart Water photo shoot cancellation and the lack of new projects on her schedule as evidence that she's expecting.

"She's thrilled," the source added.

Finally a baby for Jen!
