Videos of the Week: Rihanna's a 'Rockstar,' Kate Gosselin Dances to 'Paparazzi,' 'Glee' does Oprah

Rihanna performs "Rockstar 101" on "American Idol."

In this week's top 10 videos that had everyone buzzing: Rihanna channels her innner "Rockstar" on "Idol," Kate Gosselin performs for "Paparazzi" on "Dancing with the Stars," the "Glee" cast gets love from Oprah and Michelle Obama, Justin Bieber drums with the Roots' ?uestlove, and more.

1) Rihanna Channels Her Inner "Rockstar" on "American Idol"

Before Michael "Big Mike" Lynche was saved by the "American Idol" judges, RiRi dropped by Wednesday night's shocking results show to perform her new single, "Rockstar 101." Though it would have been nice to hear her No. 1 hit "Rude Boy" live, seeing the Barbadian singer a work a black latex suit and an electric guitar was a worthy trade-off.

Bonus Rock Star Status: Former Guns N Roses guitarist Slash performs "By the Sword" from his upcoming solo album on "The Tonight Show," with a "Team Coco" badge pinned to his shirt. Conflict of interest, much? (Watch)

2) "Glee" Gets Love from Oprah, Michelle Obama

Just a few days before "Glee's" Apr. 13 return to TV, a studio audience full of Gleeks jumps for joy as Rachel, Finn, Mercedes, Puck and company belt out their hit cover of Journey's "Don't Stop Believin'" on Oprah.

Bonus Unabashed "Glee": The cast sings "Somebody to Love," "Somewhere Over the Rainbow" and Neil Diamond's "Sweet Caroline" at the White House Easter Egg Roll. Fast-forward to the 9:00 minute mark to see First Lady Michelle Obama dance up a storm. (Watch)

3) Kate Gosselin's "Paprazzi" Dance Number

Kate Gosselin, is that really you? On this week's "Dancing with the Stars," the controversial reality mom sported a long blonde wig and a melodramatic scowl and danced the paso doble to the tune of Lady Gaga's "Paparazzi." So bad, it's hard to stop watching.

Bonus Gosselin Tomfoolery: Late-night funnyman Jimmy Fallon spoofs Gosselin's routine, with the Roots providing their version of DWTS' numbingly bad arrangement. "I was attacked by the paparazzi again this morning...I think my feelings can best be expressed in the form of dance." (Watch)

4) Justin Bieber Drums With the Roots' ?uestlove

Another must-watch Fallon moment this week came courtesy of -- who else? -- Justin Bieber, who hit the drums with the Roots' ?uestlove and spoke of his desire to have Chuck Norris play him in a biopic. Wonder how his tween admirers would feel about that casting choice.

Bonus Drummer Boy: Costa Rican newcomer Debi Nova sizzles with Shakira-like moves in the video for her danceworthy new single, the aptly-named "Drummer Boy." (Watch)

5) Cypress Hill Bring Out the 'Latin Armada'

Pass this man a Cuba Libre. Hip-hop vet B-Real of Cypress Hill gets an assist from salsero Marc Anthony and Miami rapper Pitbull in the group's new single, "Latin Armada." Yes, that's a Crosby, Still & Nash sample you're hearing on the Jim Jonsin-produced track -- and it works.

Bonus Summer Heat: The-Dream brings us more warm-weather beats and eye candy with the clip for his new single "Love King." To be played with the top down, only. (Watch)
