The Girl With The Dragon Tattoo had a budget close to $90 million, however the highly-anticipated flick only brought in $13 million during opening weekend.

When asked if that makes Dragon Tattoo a flop, one movie analyst tells E!:

"A debut of $13 million over the holiday season is equivalent to a lump of coal, especially for a film that brings along this much fanfare. With a budget approaching $90 million, plus purchasing the rights to the Millennium franchise, plus big-time marketing, this will go down as a dud."

Ouch! In positive box office news, Mission: Impossible - Ghost Protocol raked in $26.5 million, followed by Sherlock Holmes with $17.8 million. Rounding out the top three ... the newest Chipmunks flick.

We'll see if Dragon Tattoo picks up steam at the box office as the new year approaches.

Warner Bros.

After seeing this photo from the upcoming stripper flick Magic Mike, we're searching around for dollar bills!

A shirtless (and newly engaged!) Matthew McConaughey is looking oh-so-sexy alongside co-stars Alex Pettyfer, Channing Tatum and True Blood's Joe Mangianello whose nickname in the film happens to be Big D**k Richie. 'Nuff said.

The Steven Soderbergh-directed film also stars Matt Bomer and Olivia Munn. We can't wait to see these guys in action when the film hits theaters next year ... especially since the screenplay is inspired from Channing's past job as a stripper.

Lady Gaga's former assistant, Jennifer O'Neill, has filed a lawsuit claiming she was not paid for overtime that accumulated during her 13 months of employment with the singer.

In the lawsuit, O'Neill states that part of her job included "ensuring the promptness of a towel following a shower and serving as a personal alarm clock to keep [Lady Gaga] on schedule."

O'Neill claims she is owed $380,000 in overtime. The legal papers also state that the assistant was at Gaga's beck and call in "stadiums, private jets, fine hotel suites, yachts, ferries, trains and tour buses."

Although the lawsuit mentions Gaga, she is not the defendant. The lawsuit is between O'Neill and Mermaid Touring Company ...the company Lady G uses for her concerts.

Gaga's rep tells the NY Post that the lawsuit is "completely without merit."
