Britney Spears is one proud mama.

"Omg. How CUTE are my boys?!" Spears wrote on Instagram, posting a photo of herself and her sons eating popcorn in a movie theater.

The image is a sneak peek from Spears' new music video for "Ooh La La," in which sons Jayden James, 6, and Sean Preston, 7, make a cameo alongside their famous mom.

The video premieres Thursday on VEVO at noon ET.

Making their screen debut, the boys plays themselves.

Hear Britney Spears New Song 'Ooh La La'

Last month, their 31-year-old mother proudly told Ryan Seacrest on his radio show that her children acted like pros on the set.

"My oldest son, Preston, was right on cue every time they would tell him to do something in the video," she said. "They were actually really, really good on set."

The song, which is featured on the "Smurfs 2? soundtrack, was actually Spears' gift to her boys.

"They're obsessed with the Smurfs," she told Seacrest. "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."
