Hollywood's top names gathered in Beverley Hills last night to celebrate Jennifer Aniston and Justin Theroux's engagement.
The star-studded bash was held at Jennifer and Justin's Californian home and is said to have been a very 'laid-back' affair.
Guests included Demi Moore, Ben Stiller, Tobey Maguire, and Ellen DeGeneres and her wife Portia DeRossi, all of whom are said to have been wearing casual clothing for the party.
Celebrating Jennifer's upcoming wedding, twelve years on from marrying Brad Pitt and seven years after their divorce, the celebrities are said to have partied into the late hours of the morning.
Justin Theroux proposed to the Friends star on his 41st birthday last August with a huge engagement ring.
There has yet to be any official news on when (or where) the celebrity nuptials will be taking place.
