Britney Spears may not be performing in Vegas this week, but that doesn't mean she's taking it easy!

On Wednesday the pop star went to the gym in Los Angeles, and she flashed X17 photographers her megawatt smile before her workout. Britney will be back at the Planet Hollywood Resort and Casino next Wednesday for the latest leg of her "Piece of Me" residency, which runs through early March. Then Brit will have a little over a month off before the next round of shows, so she'll have plenty of time to be with her boys -- and her steady beau Charlie Ebersol!

On New Year's Day Brit posted a photo of the lovebirds, and we have to say, we haven't seen her this happy in a long time. Not only is he WAY better looking than her scummy ex David Lucado, but seems like a way better match for her. Awww!
