What had ETonline readers buzzing this week?

1. Oprah, Kim K. Send Leno Off In Song

Billy Crystal led a group of Jay Leno's star-studded friends in song as the host bid "so long, farewell" to The Tonight Show (again).

Performing to the tune of The Sound Of Music's Farewell Song, Jack Black, Kim Kardashian, Oprah Winfrey, Jim Parsons, Sheryl Crow, Carol Burnett and Chris Paul all showed up to say goodbye. "So long farewell, last night I told my folks, now I won't be the butt of Leno's jokes," Kim, 33, sang.

Oprah, 60, rounded out the musical, singing, "You really raised the bar. If you were me, you'd buy them all a car!"

It was an emotional farewell for Leno, who broke down in tears upon giving his farewell to the show, but still managed to get in some jokes. "Tonight is our last show for real. See I don't need to be fired three times. I get the hint, I get the hint," he said. "Being together all these years, very close close staff. It's kind of like graduating high school. A high school for very stupid people that have been together for 22 years."

"This has been the greatest 22 years of my life," he concluded as the audience cheered. "I am the luckiest guy in the world."

2. Channing Tatum: Right Now I'm 'Fat & Happy'

Channing Tatum recently stopped by The Ellen DeGeneres Show, in which he admitted that his famous Magic Mike physique is currently on hold!

"Right now, what me and my wife [actress Jenna Dewan] like to call it, is I am very 'fappy,'" the 33-year-old actor jokes. "I'm very fat and happy right now. I've been working for two straight years, and now it's some really needed down time."

Tatum also opened up to Ellen about his eight-month-old daughter Everly, who he claims has better taste in music than him.

"But you know how you get that first thing of not feeling cool enough for your kid, because like, you think you're the coolest thing in the world so far because she's just a little baby -- she's just a little infant. But she actually has better taste in music than I think I do. Because she will only fall asleep to really good music," he dishes.

And it turns out she has a penchant for both Prince and Drake, specifically the rapper's hit Hold On, We're Coming Home.

"[She falls asleep to] Drake, she might be conceited I'm not sure [but] The Most Beautiful Girl in the World -- Prince's The Most Beautiful Girl in the World -- she loves falling asleep to that."

Tatum appears on The Ellen DeGeneres Show Thursday, February 6.

3. 'Biggest Loser' Scandal! Is the Winner Too Thin?

From the looks of coaches Jillian Michaels and Bob Harper's face, they may have been thinking what just about everyone on Twitter and Facebook has been posting: The Biggest Loser winner Rachel Frederickson is too thin.

Rachel, a former athlete, in her early twenties and reportedly 5'3", went from 260 pounds to 105 pounds (a total of 155 pounds shed), losing 60 percent of her body weight, thus making her $250,000 richer. Upon seeing her, Jillian mouthed, "Oh my God!"

Rachel's dramatic transformation caused quite the weight debate among viewers of the NBC reality show, with many using the hashtag #anorexia when referring to her weight loss.

4. Ashton To Charlie: 'Shut the F*** Up!'

Ashton Kutcher has had enough of Charlie Sheen's mean tweets.

Kutcher, who replaced Sheen on CBS' Two and a Half Men, had a message for the 48-year-old actor on Wednesday's Jimmy Kimmel Live. "Dude, shut the f**k up!" Kutcher said to camera. "Seriously, like. Enough already. Like it's like three years later and you're still blowing me up on Twitter. Like come on dude, really?"

The 35-year-old actor did admit that it was tough getting back in the sitcom swing of things. "I thought it was gonna be easy," Kutcher said. "Like from That '70s Show, and then taking a break from doing sitcoms, like jump back into sitcoms. And it actually took me more time than I thought it would to just sort of get my sitcom sea legs again. Get back into the rhythm. And I feel like the show's really got a nice stride right now."

5. Super Bowl Scandal: Did Chili Peppers Play Live?

Though this year's Super Bowl halftime show featuring Bruno Mars and the Red Hot Chili Peppers received overwhelmingly positive reviews, it's now not without a bit of scandal -- after getting quickly called out via social media that the Red Hot Chili Peppers' guitars weren't plugged in, the band's bassist Flea has admitted to miming their show.

"Dear everybody, When we were asked by the NFL and Bruno to play our song Give It Away at the Super Bowl, it was made clear to us that the vocals would be live, but the bass, drums, and guitar would be pre-recorded," he posted to the band's website. "I understand the NFL's stance on this, given they only have a few minutes to set up the stage, there a zillion things that could go wrong and ruin the sound for the folks watching in the stadium and the t.v. viewers. There was not any room for argument on this. The NFL does not want to risk their show being botched by bad sound, period."

Fansided reported on both Flea and guitarist Josh Klinghoffer's curious lack of cords on their guitars while performing their hit single Give It Away.

Last year's Super Bowl performer Beyonce was caught in a similar scandal last January, when it was revealed that she lip synced the national anthem on Inauguration Day. She later insisted on singing live during halftime.

Bruno Mars also appeared to be singing live during the big show.
