Britney Spears has appeared at the Smurfs 2 premiere with her sons Sean Preston and Jayden James.
The singer appeared at the event at the Regency Village Theatre in Westwood, California today (July 28) after releasing her new single 'Ooh La La' from the film's soundtrack.
When she announced the single earlier this year, she revealed that she agreed to release the track because her sons are huge fans of The Smurfs.
Ahead of the premiere, the 31-year-old posted a picture of herself with Sean Preston and Jayden James, with the caption: "Getting ready with my baby boys to head to the #Smurfs2 Premiere. They are bouncing off the walls :)."
Spears posed for photographs on the premiere's blue carpet and was seen signing autographs for waiting fans.
She was also pictured speaking to collaborator Bonnie McKee and Katy Perry, who voices the character Smurfette in the film.
Perry also revealed to E! News at the event that she performed backing vocals for 'Ooh La La' along with McKee.
Spears will release her eighth studio album later this year, and is currently working with the likes of William Orbit, Sia and Danja on material for the record.
The Smurfs 2, which is out in the US and the UK on July 31, will follow the CGI creatures on a mission with the help of their human friends to find Smurfette after she is taken by their evil nemesis Gargamel.
The cast includes returning actors Neil Patrick Harris and Jayma Mays, as confirmed by director Raja Gosnell.
Katy Perry, Sofia Vergara, Christina Ricci, Hank Azaria, Anton Yelchin and more are also part of the voice cast for the family film.
