Songstress Demi Lovato has confirmed that her next single will be 'Really Don't Care', which also features British hitmaker Cher Lloyd. 

The lyric video for Lovato's forthcoming new single is due to be released tomorrow on May 14 and she announced that news as part of her '#Demiversary', which she explained is a week-long celebration to mark the fact that it's been a year since her latest album dropped. 

The superstar will head to the UK on June 1 for a one-off concert, which will take place at Koko in London and she has since revealed plans to book a European headlining tour that will have its locations decided by popularity of fans using Shazam in certain areas. 

Shortly after her London show, Lovato will perform at L.A. Pride Parade as well as appearing at the event as the Grand Marshal on June 8 and she will then sing live at the New York City Pride's Dance on the Pier in Tribeca on June 29.
