Lindsay Lohan

Lindsay Lohan is opening up about her sexuality, revealing what most have guessed from witnessing months of her near-attachment at the hip to pal Samantha Ronson.

The actress still maintains she's not a lesbian. But when asked whether she's bisexual, she tells Harper's Bazaar, "Maybe. Yeah."

"I don't want to classify myself," she continues. "First of all, you never know what's going to happen — tomorrow, in a month, a year from now, five years from now. I appreciate people, and it doesn't matter who they are, and I feel blessed to be able to feel comfortable enough with myself that I can say that."

Lohan gets candid about her relationship and her struggle to find happiness in the magazine's December issue, ostensibly crediting Ronson for bringing some stability to her life. "I think it's pretty obvious who I'm seeing," she says. "She's a wonderful person and I love her very much."

Why has she been so coy about her romance?

"It's hard. The second I start talking about whomever I'm seeing, a month or two later it's failed," said Lohan, whose past flames include U.K. socialite Calum Best.

Protecting her relationship takes on extra importance after her DUI and rehab stints in 2007, which she concedes hadn't been all fun and revelry. "I was going to clubs all the time and it was not okay," she recalls. "I was so alone."

Ronson has helped change all of that.

"I'm a different person now," Lohan says. "I'm happy."
