Looking every bit the pop star fans have loved since her debut in 1997, Britney Spears performed a sold out show at the Bill Graham Civic Auditorium in San Francisco Sunday afternoon, March 27th, 2011. Dressed in a variety of costumes accentuating her toned shape, Britney served up a high-energy show to the delighted crowd of adoring fans. The concert also featured some elaborate set pieces and backup dancers gyrating in step to Britney’s songs.

The show was hosted by ABC’s “Good Morning America” and comes just days before the highly anticipated release of her 7th album, Femme Fatale.

Here's what the 46-year-old Cougar Town actress had to share:

On her estranged husband, David Arquette: "You can't really get mad at David because he's not a malicious person. He was dealing with things the best way he could. And don't get me wrong, he was on a show for entertainment. David is smart, and David is also a showman. He knew what he was doing. I don't know what's going to happen, but I don't think he'll be doing more Howard Stern any time soon. He's not out to harm. But I'm his biggest protector. I can't help it."

On her marital struggles: "The thing is, when you get older, it's more about compatibility than it is about love. I think it's more about needing just a kind of peace and stillness. I'm kind of all over the place, and I need grounding. I want to be calm. I want to change a lot. I want to live not outside but inside. It's nothing with David; it's just what I'm searching for."

On their seven-year age gap: "Most guys aren't that mature, are they? They just don't think the way we think. I thought I had always been a little bit of a cougar with David….I don't find the whole cougar word that offensive. And also, a cougar is someone who takes care of herself and goes out with younger guys. She doesn't need a man to take care of her."
