Stiller Embarrassed By White House Visit With Gervais

The actors, who co-star in upcoming film Night at the Museum: Battle of the Smithsonian, paid a recent visit to Washington, D.C. to premiere the new movie.

Gervais had already sent his business attire to the dry cleaners when they received a last-minute invitation to the home of President Barack Obama.

But The Office star was determined to make the trip even if it meant posing for pictures in his pyjamas - and Stiller is still haunted by his co-star's crude behaviour.

He says, "I went (on the tour) with Ricky Gervais because he's in the movie. They told us to dress business. I wore a suit and tie. And Ricky Gervais, British Ricky Gervais, shows up in a black t-shirt and draw string yoga pants. It's very beyond casual - like ready to meditate or something. And then he's running around like, 'Oh, this is where our American president lives! Where's the dog?'"
