Demi Lovato has admitted that she "still can't believe" she performed with Ed Sheeran at the Hollywood Bowl.

The two singers teamed up for a version of the Brit's track 'Give Me Love' earlier this week at the massive Los Angeles venue.

It seems to have impacted Lovato hard, who tweeted on Tuesday (June 17):

"Still can't believe I played the Hollywood Bowl last night and then sang Give Me Love with Ed Sheeran...Wow..."

The US star later tweeted that she is on a health kick, with the singer eating organic food and exercising in the gym.

The former X Factor USA judge posted pictures of herself sunbathing in a bikini, as well as an image of herself sweating whilst working out.
