Heidi Klum's Naked Throwback Pic, Ian Ziering's Latest 'Sharknado' News, and Much, Much More

Here's what everybody's hootin' and hollerin' about:

Last Friday, Heidi Klum posted a nude throwback photo to Instagram (below). Some sites are calling it "super sexy," but we can't get past the deer-in-the-headlights look on her face, which seems to suggest she's trapped in a "Saw"-type situation.

Ian Ziering and Tara Reid of SyFy's "Sharknado" franchise have both signed on to appear in a third installment, set to debut in July. And judging by our interview with Ziering after the first sequel (above), we can't say we're surprised. He's probably gonna get a way bigger chainsaw this time, too.

On Friday's episode of "The View," guest host Naya Rivera ("Glee," ) criticized Justin Bieber for taking too many shirtless selfies, remarking that he "look[s] like a d*****bag." And that may be true, but in fairness, he looks like a  d*****bag with really nice abs.

Speaking of the Biebs, "Saturday Night Live" spoofed his latest Calvin Klein ads on this week's episode (below). Bieber responded by tweeting "well played," and "lol," proving that he's not completely devoid of any self-awareness. He's just completely devoid of sleeves.

NBC announced plans to follow up their highly successful live productions of "The Sound of Music" and "Peter Pan" with a live production of either "The Wiz" or "The Music Man" They also said they're looking at "casting options," which we take to mean they're watching "The Big Bang Theory" and arguing over which of the nerds would make a better Tin Man.

FOX, too, is gearing up for its own live musical event, and has reportedly recruited Julianne Hough and Vanessa Hudgens to star as Sandy and Rizzo (respectively) in a live production of "Grease" scheduled for next year. There's no word yet on who will play Danny, but it's safe to assume FOX has contacted Zac Efron about it.

Judging by her Instagram account, 18-year-old Hailey Baldwin (son of Stephen, niece of Alec) appears to be going into the family business. And no, we're not talking about acting; we mean she's trying to out-skin her cousin Ireland and Aunt Hilaria in her latest workout selfies, uploaded over the weekend:

In honor of their 50th anniversary, the surviving members of The Grateful Dead will be reuniting for a series of concerts at Soldier's Field in Chicago. If you need directions, just follow the smell of patchouli, or anyone heading north on I-35 in a Volkswagen bus.

Christina Aguilera shared her very first photo of daughter Summer Rain on Sunday (below), and as you can see, she's alreay dubbed the baby girl a "Lil Diva." And trust us, Summer is already a diva. She's always crying for attention, and demanding to be fed or burped, and expecting other people to change her when she poops. What a prima donna, right?

After defeating the Packers and the Colts (respectively), the Seattle Seahawks and the New England Patriots are officially headed to a Super Bowl that a large swath of the country couldn't care less about.

Lindsay Lohan — the poster child for safe driving — is in the process of filming a commerical for Esurance which will probaby run during the Super Bowl, reports TMZ. Our guess is that it's going to feature Lohan making light of her past accidents in a self-depricating way, so that we, the viewers, might chuckle before remembering how depressing this whole thing actually is.

The crew of "Hot in Cleveland" surprised Betty White with a Hawaiian-themed flash mob in honor of her 93rd birthday (below). We're still not sure why they went with a Hawaiian theme, though our best guess is that it matched the decor of her "Golden Girls" house. (What with their "lanai" and all.)

And finally, the Clint Eastood film "American Sniper" has reportedly broken box-office records by earning more than $90 million in its opening weekend, proving beyond a doubt that audiences like watching people shoot at things with guns. Remember that, Hollywood.
