Appearing on the Rachael Ray Show, Gwyn said, "I did a little cameo once at the beginning of Austin Powers 3, I think it was, and I got to make out with Tom Cruise. He was an amazing kisser!"
The 38-year-old went on to say that she enjoyed the round-the-clock drinking she had to do to get into character as an alcoholic singer for her new film Country Strong.
"You just get really drunk all the time," she said. "Which is awesome! At least I did anyway, it's not very professional. There's a Bloody Mary at 10am and keep it going all day!
“It was actually very liberating and amazing to play somebody who just didn't think about consequences because I'm so responsible with my life, and too worried about everybody and my kids and where's everybody going."
