It's a 2009 flashback: Mischa Barton is back in the news. 

"The O.C." alum's Beverly Hills villa is being foreclosed upon, according to several reports. 

The 28-year-old's numerous attempts to sell or rent out the home have failed and she's defaulted on her mortgage, TMZ reported. Now she's more than five months and $100,000 behind on payments, according to property records obtained by "Today" and People.

Barton bought the house in 2005 during the heyday of the real estate bubble  -- and of her "O.C." fame -- for $6.4 million, taking out a $4.2-million loan to do so, TMZ said.

The 7,607-square-foot Spanish-style home boasts eight bedrooms, 11 bathrooms and a 3,000-square-foot guest house. It's reportedly worth $8 million now.

The Fox nighttime soap, which also starred Benjamin McKenzie, Rachel Bilson and Adam Brody, went off the air in 2006. Barton followed that up with a spate of erratic behavior and a drunk-driving arrest that saw her plead no contest and get sentenced to three years' probation.

In 2009, Barton was finally committed on an involuntary psychiatric hold after blacking out under the influence of a sedative.

Though her IMDb page boasts numerous titles in production, the London-born actress' career has literally gone up in smoke: These days she's fronting Vapestick's e-cigarette ad campaign in Britain.

But if you ask her if she'd be willing to do "The O.C." again, she'd say "probably not."

"It's something I came so close to not doing," Barton recently told Metro. "I had a really great thing with film. People say be grateful for what you have but it [is] certainly not the kind of thing I was expecting it to be. ... I've kind of seen it all."

And now her home might be seeing the auction block if she doesn't reach an agreement with the lender.
