Jessica Biel is clearly one proud wife.
"A photo from the side of stage. Second night of wireless festival," she wrote.
It was just one of several tweets and pics, in fact, that Biel shared with fans while cheering on her man.
"My view at tonight's london concert. Phenomenal show. Spectacular crowd!" she tweeted on July 12, again with a photo of Timberlake doing his thing.
Biel soon followed that up with "Acoustic version of what goes around. So cool. I hope everyone can see the show!" along with yet another pic.
During the concert, Jay-Z came out and joined Timberlake to perform the hit "Suit & Tie."
It was a sneak preview of sorts as the two will be kicking off their Legends of the Summer Stadium Tour this week in Toronto.
In addition to Toronto, the dynamic duo is scheduled to stop in New York, Chicago, San Francisco, Los Angeles, Vancouver, Detroit, Baltimore, Boston, Philadelphia, Miami and Hershey, Pa., between July 17 and Aug. 16.
They'll perform in such iconic venues as Yankee Stadium, Fenway Park, the Rose Bowl and Candlestick Park.
At the Grammys this year, Timberlake spilled a little info about the tour while chatting with E! News.
"It's going to be a lot of fun," the singer said at the time. "I don't know how much I should say. It's going to be a lot of fun, I know that."
