Pixie Lott came to a school in Surrey where the kids have recorded a version of the video for her hit Boys and Girls. Ricky looks pretty pleased to see her!
Pixie gave a special gig just for the kids, but Newsround got exclusive access to the concert too.
She started off by singing Boys and Girls and then performed a medley of some of her other hits.
All the kids were really excited to see Pixie - who said she was really impressed with the version of Boys and Girls that the school recorded.
And of course Ricky was there to get all the gossip from Pixie. Check out his report see hear what she had to say!
But of course the real stars of the show were the children who recorded the video. Here they are with Pixie - she's not much bigger than them!
