Matt Damon Pictures at Lisa Snowdon's Birthday Party

Matt and Luciana Damon Hang Up Their Swimsuits For a Fancy London Party

Matt Damon and Luciana Damon partied at Lisa Snowdon's 40th.

Matt Damon attended Lisa Snowdon's 40th birthday party in London on Saturday night. Along with his wife Luciana, who looked gorgeous in a teal gown, Matt attended the UK TV presenter's bash at the Portland Place venue. Lisa and Matt are apparently great friends, having met back when she dated George Clooney. Her relationship with George was on-again, off-again from 2000 to 2005. In the years since, Lisa has stuck largely in the UK working on projects like Britain's Next Top Model and the Capital Breakfast morning show.

Matt and Luciana headed to England after a getaway to St. Barts. Matt Damon was shirtless for the vacation with Luciana, Chris Hemsworth, and a pregnant Elsa Pataky. The group hung out on a mega-yacht — complete with a helipad — for a few days, which came as a nice break from the cold for NYC residents Matt and Luciana.
