Jane Fonda was treated to a surprise performance of the saucy song rapper Mickey Avalon wrote in her honour, when pal Sean Penn invited the musician to her annual Christmas Party.
Avalon teased the film legend and fitness icon in his 2006 hit, rhyming lyrics that include, "More junk in her trunk than a Honda/I know you wanna do the Jane Fonda."
The star admits he was apprehensive about performing the track in front of the actress herself - but he was thrilled when she danced along.
In a post on her blog, Fonda writes, "Sean Penn brought Mickey Avalon to our Xmas party. He sang Do the Jane Fonda and I danced. Fun!!"
And a relieved Avalon adds, "I guess she liked the song - so that's cool. She pretty much took it at face value for what it was."
