Jennifer Aniston and Justin Theroux threw a HUGE base at their Beverly Hills mansion last night, to celebrate their recent engagement, X17online can report exclusively.
Friends like Demi Moore, Ben Stiller, Lake Bell, Ellen DeGeneres and Portia di Rossi turned out for the big bash.
Guests arrived in casual attire, with gifts. The party started around 7pm and some of the revelers, like Demi, left around 11pm.
A DJ played alternative music ... not too loud ... while the party went on inside and rain poured down outside.
Jen and Justin were engaged in mid-August while Aniston was filming We're the Millers in North Carolina. The two dated for just over a year after meeting on the set of Wanderlust.
