Lady Gaga has overtaken Oasis to become the artist to enjoy the most weeks in the UK chart.

The singer's debut album 'The Fame' has now spent 154 weeks in the top-75.

She has also been named the most searched for female on the internet in the new edition of the Guinness World Records.

Meanwhile, the late Michael Jackson is the most search for male on the internet, while Madonna is the biggest-selling female act of the 21st century in the UK.

Husband and wife Jay-Z and Beyonce have been named the year's biggest 'Power Couple', earning around $122 million through June 2009.

Pixie Lott has recorded the biggest chart jump, with her song 'Boys And Girls' climbing to number one from number 72 in one week.

Craig Glenday, editor-in-chief of this year's records book, said: "Almost two years ago, Lady Gaga and Pixie Lott were not even around so it's amazing they have broken these records.

"Every year, so many new music records are broken."

The latest edition of Guinness World Records 2011 is released today (September 16).
