The pair linked up with another couple at Lakeside Country Club in Burbank, Calif., for some friendly competition Sunday. Biel and Timberlake golf together frequently, and the foursome played the full 18 holes.
"Jessica was not bad at all," an eyewitness tells E! News. "She was athletic and able to play just fine. Justin is pretty good. He appears to practice quite a bit. He celebrated a lot after making his putts on the green!"
The couple married in October 2012, and have been together 7 1/2 years. Timberlake released his latest album, the two-part 20/20 Experience, in June and September 2013, and Biel will appear in Nailed and Shiva and May later this year.
