The event takes place this Sunday (April 12) at the Nokia Theatre in Los Angeles, with Osbourne welcoming the arriving stars as MTV’s official red carpet host.
The TV presenter and one-time singer previously did the job in 2002, going on to famously perform her cover of Madonna’s ‘Papa Don’t Preach’ later that night.
“It’s really scary and it’s really exciting,” Osbourne said of her return in an interview with People. “I get to be more creative and pick the questions and talk about fun things and not necessarily just be so focused on look.”
For Jessie J, it will be a return to TV duties after her stint as a as coach and mentor on The Voice UK from 2012 to 2013. MTV’s Josh Horowitz will also line-up alongside the two stars.
