Kesha hits a bum note on the beach in her granny-pants bikini



Pop star Kesha took a break from her Australia tour for a day of beach fun today.



The 24-year-old Tik Tok star was spotted frolicking in the surf while visiting Adelaide with friends.

She opted for a rather usual and unflattering bikini ensemble for the occasion - a black two piece which featured bizarre granny-pants with cut-outs on either side.



Still, the singer looked confident as she strutted along the foreshore in her swimsuit and even stopped to do a sun salutation yoga pose.

Off duty: The singer is currently in the country on tour

Kesha has been performing in various cities across the country, including a high-energy 45-minute set at the Future Music Festival in Sydney earlier this week.



She has also just unveiled the video for her song Blow which stars former Dawson's Creek star James Van Der Beek.

She is set to enjoy chart success of a different kind too - she helped to pen Britney Spears' latest single, Till The World Ends, for her new album, Femme Fatale.



'I consider myself a songwriter before and above everything else, so it's an honour to write for one of pop music's biggest icons,' Kesha says.

'And I hope it gets everyone's ass on the dance floor!'

Revealing the inspiration behind the track, she added: 'That song is me imagining her and any female musician touring the world.



'You know, when you go out, and you're having an amazing, magical night and you don't want to go to sleep and you want it to last until the world ends.'
