Ricky checks out school's Pixie Lott video
Pupils from a primary school in Surrey have become internet stars after recording their own version of the Pixie Lott hit Boys and Girls.
About 200 kids from Amesbury School in south-east England sang the song to raise money for charity.
Their video has had more than 80,000 hits online.
And even Pixie's seen it! She said on her website: "I'm so moved by this - those kids are so talented and it's for such a good cause."
The track is raising cash for the charity CRY, which raises awareness of heart conditions, especially among younger people.
One of the school's former pupils died suddenly from a heart condition.

If you think the song and video seem really well made, it's because they had a bit of help from a parent who runs a record label!
In the video, a classroom of kids start singing and dancing behind their teacher's back. When he realises what's going on, he starts joining in!
