Usher, Justin Timberlake, Will.I.Am Surprise Fans On 'Oprah'

Usher also performs in studio and dances with Winfrey.

Usher, Justin Timberlake, Cher and the Black Eyed Peas' Will.I.Am appeared on "The Oprah Winfrey Show" on Monday afternoon (May 10) as part of the talk-show host's "Star-Studded Harpo Hookups" special.

Timberlake appeared via Skype and gave away a pair of golf clubs to a lucky fan who was surprised to learn she'd be taking lessons on the links with the "Cry Me a River" star. The woman, who claimed to be JT's biggest fan, is set to be married soon, and her fiancé helped organize the surprise. The fan told Timberlake that she listens to his CD when she's having a bad day to feel better.

Another fan, named Josh, was flown to a Cher concert by his partner but got "hooked up" by getting a chance to meet the diva herself backstage.

Peas frontman Will.I.Am took cameras on a tour of his childhood home in Los Angeles and later helped out a family that was struggling financially. The superstar producer helped the family avoid foreclosure. "That's a great hookup," Winfrey beamed after the producer's announcement.

Usher then appeared in the studio at the end of the show to perform his #1 hit "OMG," produced by Will.I.Am. The singer had fun during his appearance, dancing with Oprah and even tossing his designer shades toward her after he walked away from their twirl.

Oprah was fully engaged in Usher's performance, especially during the song's chanting "Oh, oh, oh," which she repeated while wearing Usher's shades.
