Mashup: Britney’s ‘Till the World Ends’ Mixed With Adele’s ‘Rolling in the Deep’

A new mashup features a battle of Brits -- Britney Spears and British singer Adele. The track, courtesy of knob-twiddler Jarod Ripley, melds Britney's latest hit, 'Till the World Ends,' with Adele's single 'Rolling in the Deep.'

The resulting mix, 'Rolling Till the World Ends,' speeds up Adele's vocals and matches them to the dance beats of Britney's tune. Ripley, who also created a mashup video to accompany the track, has previously retooled cuts by Lady Gaga and Bruno Mars, among others.

Britney's latest album, 'Femme Fatale,' debuted at No. 1 on the Billboard 200 chart last week, about a month after Adele's sophomore disc, '21,' topped the chart. Britney will hit the road for a North American tour beginning June 17, while Adele's North American trek kicks off May 12.
