LOS ANGELES —  Looking happy and healthy, Britney Spears paraded her new bikini body and spent time with her two sons at a party last weekend, while fans got a look at two new MTV promos featuring the pop star and VMA host Russell Brand.

The former teen queen's promos with Brand have fueled speculation that she could be returning to the stage at next month's MTV Video Music Awards after last year's notorious flop.

"You are Britney Spears, right? I'm not dreaming this am I," asks the British comedian in one ad, which also includes a 9,000-lb. elephant in the background, to which they are both apparently oblivious.

"No, this is real," responds Spears, looking sleek in a fitted black dress — and she pinches him to prove it.

In the second spot, Brand, who is well-known in the U.K. but not in the U.S., presses Spears to remember his full name — which she doesn't.

"You will remember that name because I think pretty soon it's going to be your surname," he says. "Britney Brand."

MTV has to declined to comment on whether Spears will perform at the VMAs. She's nominated for best female and best pop video.

Spears is also working on a new album this summer, another sign that her condition is improving after almost two years of odd behavior.

She has also reportedly completed her first sit-down interview and photo shoot in nearly two years for Friday's issue of OK! magazine.

Last month, she settled a long-running dispute with ex-husband Kevin Federline, which allows her additional visits with her young sons while Federline retains custody.
