Peter Dinklage, who plays the riveting Tyrion Lannister in "Game of Thrones," has been cast in "X-Men: Days of Future Past," according to Deadline.com.

Director Bryan Singer has assembled a collection of his original "X-Men" cast with returnees from "X-Men First Class," with Dinklage supposedly signing on for a "key" role.

That's great. Hopefully he'll either play Batman or a young Han Solo.

Dinklage won an Emmy for playing as Tyrion Lannister, arguably the craftiest and most sane member of his royal family on "Game of Thrones."

Singer apparently loves to announce casting decisions via Twitter, but Deadline doesn't say whether he's tweeted about Dinklage yet. Singer has used Twitter to announce Jennifer Lawrence, Hugh Jackman, Patrick Stewart, Ian McKellen, James McAvoy and Michael Fassbender.

'CHUBBY CHECKER" UPSETS CHUBBY CHECKER: Chubby Checker is suing the makers of an app that allows women to estimate the size of a man's ..., er ...manparts.

That's right. It's called the Chubby Checker.

This is one of those stories that makes me proud to have gone to journalism school.

According to TMZ, the 71-year-old music legend has filed a lawsuit against Hewlett-Packard and Palm (yes, palm), saying they violated the trademark on the name "Chubby Checker" ... by releasing "The Chubby Checker" app, which "enables women to estimate the size of a man's penis based on his shoe size."

That's really funny. Me and my size 18 feet can't stop laughing hysterically.

"I don't want people to go around calling me a penis," Checker told TMZ on Thursday. "They're selling a penis package named Chubby Checker ... I'm upset about that."

A rep for HP released a statement saying, "The application was removed in September 2012 and is no longer on any Palm or HP hosted website."

Apparently, the app has been around for a while. Checker said the companies ignored his cease-and-desist letter in 2012, so know he's taking them to court.

According to the suit, Chubby not only wants the companies to shut down the app, he also wants a ton of money for damaging his reputation.

I'm not sure how this damages his reputation, unless we wears very small shoes.

LADY GAGA CANCELS TOUR: Lady Gaga has canceled the remainder of her "Born This Way Ball" tour after suffering a hip injury.

"After additional tests this morning to review the severity of the issue, it has been determined that Lady Gaga has a labral tear of the right hip," tour promoter Live Nation said in a release. "She will need surgery to repair the problem, followed by strict down time to recover. This unfortunately, will force her to cancel the tour so she can heal."

So I guess after the surgery, her hip will no longer be able to say it was born that way.

Initially, the singer thought she'd only have to cancel four dates. But apparently her hip disagreed. There's no word on when shows may be made up.

The Chicago Tribune reported that the 21 canceled concerts could cost Gaga and the concert industry more than $35 million in lost revenue.

Among the shows canceled were dates in Chicago, Detroit, Philadelphia, New York, Boston, Atlanta and Miami.

CHRIS BROWN AND DRAKE BLAME EACH OTHER: Chris Brown and Drake are going after each other in court their big brawl last June at W.i.P. nightclub in New York City, according to TMZ.

French model Romain Julien has sued Brown, Drake and the club for the injuries he said he suffered during the bottle-throwing fight.

Now both Drake and Brown have filed legal documents in which they point the finger at each other.

That's very gangsta of them. I guess telling on each other to the mom's didn't work out very well.

Drake and Brown each say they were not responsible for the fight and want the other to pay any damages in the event the Mr. French model wins his suit.

CRANK CALLS COMING FROM KATIE COURIC'S HOUSE: Something is happening at Katie Couric's house at 2 a.m. every Tuesday.

No, this isn't another icky Larry King story.

New York City police said Thursday they had been called to Couric's Manhattan home several times recently because of 911 calls traced to a phone listed there, according to the Associated Press. Each time, the 911 operator apparently only hears only static, but police are compelled to answer each call.

Come on, Larry. Go get a hobby. Learn how to feed pigeons in the park or something.

Couric told the audience of her talk show about the strange calls this week.

Police say they are investigating whether something's wrong with her phone or if Couric is the victim of a high-tech prankster. Couric called New York City Police Commissioner Ray Kelly to ask advice on what to do, and is awaiting the results of the investigation.

I can imagine that the New York City Police Department has nothing better to do than burn resources on finding out who's crank-calling from Katie Couric's house. It's probably safe to say she can hire a private detective to look into the matter. Or at least guard her phones every Tuesday.

The calls were first reported in a New York Daily News story headlined "Katie's 911 Hell."
