Jessie J Covers Taylor Swift's 'I Knew You Were Trouble'

Jessie J invoked Taylor Swift to help promote her forthcoming album, Alive, by covering Swift's "I Knew You Were Trouble."

Jessie covered the hit single during a recent appearance on BBC Radio 1's Live Lounge. She turned the poppy song into an unplugged number, while adding her own soulful spin.

She was appearing to promote Alive, her sophomore studio album and first since 2011's Who You Are. Thus far, two singles have been released from the LP: "Wild," and "It's My Party." "Square One" was also released as a promotional single.

Alive features a number of guest appearances, including Becky G ("Excuse My Rude"), Big Sean and Dizzee Rascal ("Wild") and Brandy ("Conquer The World").
