Calvin Harris has gone straight to the top of the singles chart with his new song I'm Not Alone.
The Scottish singer and producer, who teamed up with Dizzee Rascal on last year's number one Dance Wiv Me, has knocked Lady GaGa off the top spot.
Her song Poker Face is at number two. AR Rahman and the Pussycat Dolls have stayed at number three with Jai Ho.
Ciara and Justin Timberlake's new single was the second highest new entry reaching number six.
But it wasn't all bad news for Lady GaGa. She's still number one in the album charts with The Fame.
