New York, New York - After singer Justin Timberlake was arrested for drunk driving, rumors of tension in his marriage to Jessica Biel swirled. But now, she's made a surprise appearance at her husband's concert!

A video shared via Instagram shows Jessica dancing away to the 43-year-old song during his concert at Madison Square Garden on Tuesday.

Just a few days ago, rumors of the couple's break-up surfaced after the actor was spotted in New York without her wedding ring.

As reported by PEOPLE, the 42-year-old is said to have been unhappy about Justin's arrest for driving under the influence while in the Hamptons last week.

Jessica, who is currently filming a new movie, is said to have seen the incident as a negative distraction from her work.

"She doesn't like any attention on the family, especially not negative," an insider said.

Nevertheless, Jessica is standing by the Cry Me a River singer. He's a good father and husband, and according to an insider, she would stay by his side forever.

Despite his fears, the arrest did not ruin the world tour, and JT will next perform in Boston, Massachusetts, on Saturday.
