Elvis Presley and Britney Spears team up for epic 'Toxic Las Vegas' mash-up

After joining forces with Sir Elton John last year, Britney Spears has now teamed up with the late Elvis Presley for one epic mash-up.

In celebration of what would have been the King of Rock ‘N Roll's 88th birthday, the pop Princess and RCA Records have released 'Toxic Las Vegas: Jamieson Shaw remix,' the full-length mash-up from ELVIS.

The mash-up takes parts of Elvis' 1964 song 'Viva Las Vegas' and Britney’s 2004 single 'Toxic' to create an infectious track.

'Toxic Las Vegas' marks Spears’ first single since she teamed with John for 'Hold Me Closer,' a duet that combined elements of Elton’s 'Tiny Dancer,' 'The One' and 'Don’t Go Breaking My Heart.'

The collaboration was her first new song since 2016, following the end of her 13-year-long conservatorship in November 2021.
