Lately, we've only been catching Jennifer Aniston and her beau John Mayer separately - but last night, they set out for a double date with one of Jen's best Friends!

We caught Jennifer and John sneaking out of STK after meeting Courteney Cox and David Arquette at last night's big OmniPeace event. Jen and John did their best to evade the paps' attention, arriving at the restaurant an hour apart - but any time these two get together, we can't help but take notice!
