'Nobody's Perfect' chart-topper Jessie J has revealed the name of her forthcoming tour's main support act. 

Writing on Twitter to her Heartbeats just an hour ago, July 5, she explained that UK grime artist and rapper Devlin will join her extensive string of dates later this year in October:

"This tour I wanted to have someone tour with me who I respect, who is super talented, I love listening to and who is an amazing performer.... @DevlinOfficial welcome to the #heartbeattour #essexking :)"

The pair have collaborated live on stage before and are not only familiar with each other's music, but are friends too. Watch them perform 'Price Tag' together below:
