Pixie Lott and Lady Gaga set music records
Pop stars Pixie Lott and Lady Gaga have made their debuts in the Guinness World Records for their musical achievements, it has been announced.
Lott has been included for her single, Boys And Girls, which made the biggest jump to number one ever, climbing from number 72 in just a week.
Lady Gaga has set the record for most weeks in the UK chart, clocking up 154 weeks in the top 75, beating Oasis.
She has also been named the most searched for female on the internet.
The previous record holder had been former governor of the state of Alaska, Sarah Palin.
Editor-in-chief of this year's records book, Craig Glenday, said: "Almost two years ago, Lady Gaga and Pixie Lott were not even around so it's amazing they have broken these records.
