"J.Lo, Phase Two" isn't a new summer movie — it's a state of mind for the actress-singer. "I feel like this is my phase two, like it's a new beginning," Jennifer Lopez (search) tells InStyle magazine in its August issue. "Like everything I did before really doesn't matter."

After two failed marriages and her much publicized romances with Sean "P. Diddy" Combs (search) and Ben Affleck (search), the 34-year-old pop star seems intent on not leaving a trail of glitter (and gossip) wherever she goes.

"Maybe I was a little bit careless in the past," she says. "I'm not a perfect person. I make mistakes. I just feel like I'm in a better place about who I am. I follow my heart. That's the one thing I can say about myself. And I love that about myself."

In early June, Lopez reportedly married singer Marc Anthony (search) in a small ceremony at her Beverly Hills, Calif., home. All she'll say about Anthony is, "We have a great working relationship. I have to keep my work and my personal life separate. Otherwise it gets blurry and it gets messy."

However, she'd like to co-star in a film with Anthony based on the life of salsa singer Hector Lavoe. "He's kind of like a Billie Holiday, a tragic singer," she tells the magazine. "It's a love story between a husband and wife."
