The Telephone video has been viewed 22 million times on YouTube
Eccentric US pop star Lady Gaga has scored a double in the UK charts with both her single and album reaching number one.
Telephone climbed 11 places to give the singer her fourth UK number one single, while The Fame went back to the top of the album chart for a third time.
The success comes amid controversy over Telephone's music video, featuring a mass murder story and a lesbian kiss.
Last week's number one - Pass Out by Tinie Tempah - fell to two.
In the album charts, a second collection of songs by the cast of hit high school drama Glee soared from 91 to second spot, while Boyzone's Brother and Gorillaz's Plastic Beach dropped to three and four.

There were two new entries in the album chart, with Sweet 7 by the Sugababes the highest entry at 14 and White Stripes' Under Great White Northern Lights at number 25.
Meanwhile, Lady Gaga's lawyer has responded to a legal claim against the singer from a music producer who says he helped launch the singer's career.
Rob Fusari, who is credited on Lady Gaga's album, is suing the pop star for $30.5m (£20m) alleging she denied him his share of song royalties and merchandising revenue.
According to the lawsuit, Lady Gaga and Mr Fusari formed a business partnership called Team Love Child LLC in 2006 to promote her career - of which Mr Fusari's share was 20%.
Mr Fusari also claims he came up with Lady Gaga's stage name and helped get her record deal, but she dropped him as her career took off.
Gaga began her career as piano-playing singer Stefani Germanotta
However the singer's lawyer, Charles Ortner, said in court documents that the agreement at the heart of the suit were "unlawful".
Mr Ortner said the arrangement was "structured in such a way as to mask its true purpose - to provide to the defendant's unlawful compensation for their services as unlicensed employment agents".
He added Mr Fusari and his company violated statutes that prohibited them from "acting as employment agents without a licence and charging Lady Gaga an unlawful fee for their purported services".
But Mr Fusari's lawyer called Mr Ortner's response "ludicrous" in an e-mail to The Associated Press.
"Fusari is a partner in Team Love LLC with Gaga and her father. Rob was no more of an 'agent' for her than she is a Roman Catholic nun," Robert Meloni said.
