Britney Spears recently released a music video for her song "Ooh La La!" and in the video are her two sons, Sean, 7, and Jayden, 6.
The video also features her 5-year-old niece Maddie.
In it, the kids are watching The Smurfs 2 in theaters. The song is featured on the soundtrack to the movie.
She said the boys were "really, really good on set" and said "Sean was right on cue every time they would tell him to do something. Later on, I got to see what they actually did on camera and it was adorable."
Spears said it was fitting, as her boys are obsessed with the cartoon.
"We've seen The Smurfs movie a million trillion times."
