Jennifer Aniston pregnant in hilarious new SmartWater ad

The actress shows off a huge baby bump in the new SmartWater clip - but surprise, surprise, it's not real

We could hardly believe our eyes when we set eyes on snaps of Jennifer Aniston pregnant, with a enormous baby bump blossoming from her stomach. That was, until we realised the snaps of Jen's huge tum weren't real.

Proving she'll go to just about any lengths for advertising, the actress has shot a hilarious new advert for US brand SmartWater, which shows not only her expanding waistline, but also the row of Jennifer Aniston wigs she has lined up at home.

The spoof, CCTV-style clip begins with a cameo from top presenter Ryan Seacrest, who announces: 'Some breaking news now, Jennifer Aniston's home security tapes have leaked online from an unknown source. From inside the actress’s home - shocking revelations.'

Next, the footage cuts to Jen in the kitchen of her Hollywood home, stripping off a super strength band from around her waist to reveal a huge baby bump.

And she's not only pregnant, it's triplets!

'Ahh, that's so much , how are my little triplets doing? You must be so thirsty!' Jen remarks, before swigging on her all-important SmartWater bottle.

Later the actress is pictured 'working out' as muscly trainers lift her up and down, before thanking staff for filling her swimming pool entirely with bottled water.

The hilarious vid ends with Jen staring into a mirror at the end of the day, shockingly pulling off her Jennifer Aniston wig to reveal dark curls underneath.

Well Jen, we've certainly never seen you like that before!
