The pair joined Matt Damon and Argo producer Grant Heslov for a night out at the Grill Royal and, while Stacy kept it low-key in a black mac and trousers (red lips added a flash of glamour), George was having a not-as-good-as-Tom-Selleck's moustache moment.
Looks like this A-list couple are still going strong for now... See all the stars who recently decided to go their separate ways:
Heidi Klum and Seal
An odd match but a lovely couple, so we were really sad to see Heidi Klum and Seal split up in January 2012, after seven years of marriage. The couple went on to have a public war of words when Hedi went public with her relationship with her body guard, with Seal saying: "I would have thought Heidi would have shown a little bit more class before deciding to fornicate with the help." Ouch.
Tuilsa and Fazer
They had spent ages avoiding questions about their relationship but not long after going public with their romance, N-Dubz bandmates Tulisa and Fazer split in January 2012. The 'X Factor' judge then went on to briefly date 'Skins' star Jack O'Connell.

It was the most controversial relationship of 2011, but Harry Styles and Caroline Flack only confirmed their romance when it ended in January 2012.

Mollie King and David Gandy
The Saturdays singer Mollie King split from model boyfriend David Gandy in April 2012, and went on to be briefly linked to Prince Harry. Meanwhile, David spoke out against his ex and claimed his "perfectionism" was the reason the relationship ended. Ouch.
