Charlize Theron on marriage, gay marriage and the closets

Charlize Theron has decided marriage isn't for her, but still thinks anyone who does find the institution important should be allowed to marry.

Meanwhile, she worries her "bit of OCD" when it comes to closets might hurt her in the long-term-relationship department.

"I really want for myself a long-term relationship, and I have been in long-term relationships, and so ... that's the kind of union that I want," the actress said Wednesday on "Piers Morgan Tonight." "The actual ceremony is not something that's important to me."

Theron said in 2009 that she would not marry then-boyfriend Stuart Townsend unless same-sex marriage were made legal. After nine years together, she broke up with him in the wake of a Christmas 2010 trip to Mexico.

So, now that she's single -- there's the closet thing.

"I have a thing about things that are hidden," Theron said. "Like I will -- yes, I have a hard time, especially when I'm, like, renting a house if I'm working on a film and I don't know what's in all the -- I have to know what's in all the -- this is so pathetic. I cannot believe we're talking about this."

Pressed for details, she revealed that upon arrival in a new place, the first thing she does is inspect every closet and drawer. Then she has to put things where they belong, in a manner that allows access a certain way, and -- did she mention, Piers, that this is pathetic?

"Seriously, would you stop talking about it? Really beginning to freak me out now," she said. "I am single. I need to find a man. ... This is not going to help."

Somehow, we can't imagine it hurting that much either.

George Clooney, Elisabetta Canalis "Bickering" Nonstop Pre-Split

What went wrong with George Clooney and Elisabetta Canalis?

After two years together, the couple announced their breakup to Us Weekly and the world on Wednesday.

A Clooney insider told Us there were major signs of trouble for the actor, 50, and Italian model, 32, during their New Year's getaway in Mexico.

"She drove him nuts," the source says, explaining there was "non-stop bickering over little things...He would only hang out with his friends, and more or less left her to herself and her friends."

Clooney, who's had very few long-term relationships in his life, had been "creating distance" for many months, the source added. His excuse at the time? "Work. [He] was knee-deep in pre-production on a couple projects."

One of those projects was Gravity; he and costar Sandra Bullock are reportedly wrapping up that thriller in London.

Clooney famously swore off remarrying, telling Piers Morgan in January that he wouldn't walk down the aisle again after his failed union with actress Talia Balsam in the early '90s. Italian model Canalis however, seemed more invested in the institution. "I am a firm believer in marriage," she said in a June interview with Italian magazine Chi. "In the future I will be married, but for the time being I am happy as I am."
