Lily Allen may just have one up over her rivals Girls Aloud as the Smile star is set to duet with Blondie legend Debbie Harry

Mouthy Lil' will duet with the Harry as the pair come together to cover the Blondie classic Heart of Glass.

The much anticipated performance will be part of the Summer Concert series shown on big US show, The Today Show on May 25 (tomorrow night).

Surely, another blow for Cheryl and co, who may be on a UK Arena tour at the moment, but are still no further to cracking the States.

Debbie Harry is set to release a new solo album, Necessary Evil on August 7.
