Avril Lavigne Videos: Avril Lavigne live perform in oprah show: We've got to hand it to you, Big O! We've enjoyed ALL of these duets! Bravo! Oprah Winfrey invited a slew of rocking ladies, past and present, to perform together on the show. So far, we've heard from Stevie Nicks and Sheryl Crow and from Miley Cyrus and Joan Jett. Closing out the day is a flawless performance of Love Is A Battlefield from Pat Benatar and a very nervous Avril Lavigne! She's so shell-shocked, she can't even bear to look at Pat - who, BTW, looks phenomenal!
