Ke$ha has admitted that she would like to join Britney Spears for her 'Femme Fatale' tour.
The 24-year-old singer-songwriter, who wrote Spears's recent single 'Till The World Ends', has revealed that she would love to join the star in performing the track during her current world tour.
"I really hope we can make it work," Ke$ha told the Daily Star. "I know people who saw some early previews of Britney's show and said it was amazing - so I can't wait to go myself.''
Spears released a remix version of the track back in April, which included Ke$ha's vocal as well as a rap intro from Nicki Minaj.
The 'Blow' star will take to the stage for this weekend's Glastonbury festival, as well as performing at T In The Park and headlining a handful of gigs in July.
Ke$ha recently claimed that she is "proud" of writing the track for Spears, stating that it "solidifies [her] as a songwriter in the pop world".
Don't act like y'all don't know the Bleeding Love-hitmaker. Everybody knows her ground-breaking songs and her 2.5 octave vocal range. I mean, please, do y'all live under a rock?
It was all in good fun.
