We recently reported that the OLSEN TWINS partied it up in Nashville but we were uncertain exactly why but we now have confirmation from the source itself MARY-KATE OLSEN. In a recent interview with DAVID LETTERMAN, MARY-KATE said that they were in Nashville for their twenty second birthday. The twins spent a majority of their time at Bonnaroo and MARY-KATE says that they traveled with eight people and stayed in bunks on a bus! From the looks of this interview MARY KATE was still styling her Bonnaroo hair…I guess she likes the messed up hippie look.

MARY-KATE seemed a bit uneasy while interviewing with LETTERMAN and it was obvious that she was “off”. She apologized to LETTERMAN and said that she was just so tired! LETTERMAN may believe her but I think we know the truth…she’s still coming off those mushrooms!
