Rooney Mara's Low-Key "Late Show" Visit

Out for another day of “American Idol” duties, Jennifer Lopez was spotted arriving to auditions in Pasadena, CA earlier on Wednesday afternoon (December 14).

The “On the Floor” songstress was dressed in a wintertime chic ensemble as she hopped out of a chauffeured SUV before heading inside for the day's taping session.

The outing comes amidst a report from the Chicago Sun-Times claiming that J. Lo is getting rid of all reminders of her marriage to Marc Anthony - including the bling.

Their insider alleges, "J. Lo also reportedly is quietly selling all the jewelry Anthony gave her -- and he gave her quite a lot."

The source adds, "When Jennifer moves on, she totally moves on," something which her new backup dancer flame Casper Smart "will likely discover he will 'disappear' when she tires of him too."

Fresh off of an overseas flight from Sweden, Rooney Mara made a low-key entrance into the Ed Sullivan Theatre in New York City on Wednesday afternoon (December 14).

The Lisabeth Salander actress was on-hand for an appearance on 'The Late Show with David Letterman' to promote her upcoming movie "The Girl with the Dragon Tattoo".

Of the film, Miss Mara recently spoke with Allure about the changes she's made (including a nipple piercing, shorter hair and new style preferences) due to the acclaimed role.

Dishing on her new body jewelry, Rooney confessed, "I thought, 'She has it in the book, and she should have it (in the movie). Because of all the tattoos and the makeup and the piercings, and the physical transformations my body has to go through, it would always feel sort of like I was in costume, even if I was naked. It just felt like a good one to get - a necessary one to get."

As for her chopped locks, the 26-year-old said, "People always ask, 'Were you crying when they cut your hair?' And it didn't freak me out at all. I was really happy to do it."

And, as for ditching her "girlish" wardrobe, Mara told, "I used to wear a lot of girlie, frilly things, now I buy things that are more comfortable, and more utilitarian, and sort of boyish."
