Jessica Biel sings along, dances during her husband Justin Timberlake's concert

Jessica Biel has been enjoying her husband, Justin Timberlake’s return to music almost as much as Justin.

The 30-year-old actress, who married Timberlake in October 2012, accompanied her husband to the Brit Awards on Wednesday. There, he performed his new song, “Mirrors.”

“My Huz just killed it on the Brits,” Biel praised on Twitter following Timberlake’s performance. “And the London fans are the tits!”

Justin wasn’t done performing, though. After The Brits, he performed hits new and old at a post-awards concert.

TMZ reported that his wife Jessica, who just may be his biggest fan, was caught dancing during a performance of “Sexyback.”

At the post-awards concert, a source for Entertainmentwise also revealed that Jessica sang along to his songs. She "knew the lyrics to all of his songs," which made for a "sweet" moment. According to the source, you could tell she was proud of him.

Timberlake is set to release his long-awaited, highly-anticipated new album, The 20/20 Experience on March 19, so there will be many more performances that will have Jessica Biel dancing and singing along.
