Calvin Harris shoots to top of chart

LONDON (Reuters) - Scottish singer-songwriter Calvin Harris shot straight to the top of the UK singles chart on Sunday with "I'm not alone," dislodging U.S. glam diva Lady Gaga, the Official Charts Company said.

It is another success for the 25-year-old who collaborated with British rapper Dizzee Rascal on "Dance Wiv Me," which also reached number one in Britain last year.

Lady Gaga's "Poker Face" slipped to number two after three weeks at number one.

AR Rahman featuring the Pussycat Dolls remained in third spot with "Jai Ho (You Are My Destiny)" while synthesizer duo La Roux moved up three spots to number four with "In for the kill."

Ciara featuring Justin Timberlake was the second-highest new entry with "Love Sex Magic" at number six.

In the album chart, Lady Gaga clung to top spot with "The Fame" while Doves stormed straight in at number two with "Kingdom of Rust," their fourth album.

Kings of Leon slipped a notch to number three with "Only by the Night" and singer Annie Lennox's "The Collection" also dropped a spot to number 4.
