Ashlee & Jessica Simpson Duet!

Ashlee and Jessica Simpson might be very busy ladies, what with Ash having babies with Pete Wentz and Jess getting married for a second time, but it didn’t stop the pair grabbing a mic for a festive duet.

Dressed in co-ordinating frocks (aww) the ladies totally kicked ass on a cover of Merry Xmas (War Is Over), but who do YOU like best?
