Katy Perry equals US chart record with fifth number one

Katy Perry has equalled a US chart record after having a fifth number one single off the same album.

The singer's latest track Last Friday Night (T.G.I.F.) has made it to the top of the Billboard Hot 100 after being kept at number two by LMFAO.

The other four chart toppers off Katy Perry's third album Teenage Dream were California Gurls, the title track, Firework and E.T.

Michael Jackson set the original record in 1987 with his album Bad.

Katy Perry is the first female artist to have five number ones off the same album in the 53-year history of the Billboard Hot 100 singles chart.

She broke the Billboard Pop Songs Chart record, which is based on radio airplay, earlier this month.

Michael Jackson scored his five number ones over a shorter period than Katy Perry but the 26-year-old has spent longer at the top of the chart.

So far, her singles have spent 18 weeks at number one.

Katy Perry has also broken the record for the most consecutive weeks (66) in the Billboard chart's top 10, which was previously held by Swedish act Ace of Base (48).

According to Nielsen SoundScan, Teenage Dream has sold 1.7 million copies so far.

The singer is in the middle of her California Dreams world tour.
