Michelle Williams: 'Tonight Show With Jay Leno'!

Michelle Williams makes an appearance on The Tonight Show With Jay Leno on Thursday (January 5) in Burbank, Calif.

The 31-year-old actress talked about her Golden Globe-nominated role in My Week With Marilyn, her love for the subways in NYC, and her recent vacation in Mexico, which turned out to be a bit more adventurous than relaxing.

“I’m still a little sore … horseback riding,” Michelle shared. “I thought I was [an experienced rider] until I went on this trip.”

“I thought it was going to be one of those slow, you take a lot of photos, take in the beautiful scenery. We went down ravines. We went trekking. It was an 8-hour horseback ride,” she added. “I likened it to being piggy backed by a drunk person.

FYI: Michelle is wearing Jason Wu‘s black/ivory silk gazar dress with “splattered” Swarovski Elements from the Spring 2012 collection.
