It looks like the tabloids have been right all along! RumorFix has learned that actress Jennifer Aniston is pregnant … just not with a real baby like the gossip mags tend to claim every month.

Aniston and a faux baby bump are the stars of a new spoof ad for glacéau’s smartwater. In a viral video clip, the Friends actress wears a prosethic belly while unwinding at home.

The tape – which appears to be security footage filmed inside Aniston’s LA mansion – also shows her crashing a sports car, chastising an alien and revealing that her famous locks are actually fake.

The viral vid features cameos by funnyman Jimmy Kimmel and American Idol host Ryan Seacrest. It also reveals Aniston’s swimming pool is filled with smartwater.

The 43-year-old actress, who is engaged to Justin Theroux, has been the face of the bottled water brand since 2010.
