Britney Spears may be one of the biggest superstars on the planet, but to her kids, she's just "mom."

"My sons are 6 and 7, so they're just now getting to the stage where you can't kiss mommy in front of friends," she told Ryan Seacrest on Monday of her two children with ex-husband Kevin Federline. "They're getting what's cool and what's not."

Spears, 31, debuted her new single "Ooh La La" on Seacrest's radio program, "On Air with Ryan Seacrest," and said that the song, which is featured on the "Smurfs 2? soundtrack, was a gift for her boys, Preston, 7, and Jayden, 6.

"They're obsessed with the Smurfs," she said. "We've seen 'The Smurfs' movie a million, trillion times and they were told they could be in the video and all this cool stuff, so that's the reason why I did it."

In fact, when the music video premieres in a few weeks, expect to see Preston and Jayden front and center. Spears, who is planning to release a new album by the end of the year, said the boys play themselves and can be seen checking out their famous mother on a monitor.

"They were, like, acting, and my oldest son, Preston, was right on cue every time they would tell him to do something," she gushed. "It was adorable!"
