Rainn Wilson, Jason Biggs
Celebrity sightings are fairly common at the U.S. Open tennis tournament, but on Thursday night, they'll be on the court rather than in the audience.
Jason Biggs and Rainn Wilson are teaming up for a "battle of the sexes" against former champions Chris Evert and Monica Seles Thursday night in Arthur Ashe Stadium. The Today show's Al Roker will serve as a chair umpire.

It remains to be seen how the Office and Orange Is the New Black stars' tennis skills will measure up against Seles and Evert, but Wilson at least has an outfit picked out for the event.
"Me & @JasonBiggs will be playing Chris Evert & Monica Seles at the @USOPentomorrow," Wilson tweeted Wednesday. "My shorts will be soooo tight!"
The match, which begins at 7 p.m. ET, will be broadcast live on the Tennis Channel and can also be streamed at www.usopen.org.
