The singer, 36, tweeted the news along with a video featuring Jimmy Fallon.
"I DO have the time. Half the time...#PepsiHalftime #SBLII @Pepsi @NFL @JimmyFallon @FallonTonight," Timberlake wrote.
This year will be Timberlake's third Super Bowl halftime performance, the most for any entertainer, according to The Associated Press. His performance with Janet Jackson in 2004 shocked the country with what became known as a "wardrobe malfunction."
In a planned move, Timberlake ripped off part of Jackson's top during the singing of "Rock Your Body." CBS was fined $550,000 by the Federal Communications Commission for indecency over the incident but the penalty was later overturned.
"That won't happen this time," Timberland said when asked about the incident in an interview aired during NBC's "Sunday Night Football."
The NFL tweeted an image promoting the show.
The Super Bowl takes place on Feb. 4 in Minneapolis, Minnesota.
