"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," Paltrow, 38, tells the host on Friday's Rachael Ray Show. "He was an amazing kisser!"
As for her current role in Country Strong, Paltrow confessed to some transgressions from her normally clean-living philosophy to help her get into character as an alcoholic singer.
"You just get really drunk all the time," she says. "Which is awesome! At least I did anyway, it's not very professional. There's a Bloody Mary at 10 a.m. and keep it going all day!"
The thrill, she added, was stepping outside her regimented life.
"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," Paltrow says.
Aside from the daily Bloody Marys, Paltrow jokes that she'd probably only be able to perform at the Oscars "maybe with some Xanax!" But added, "I've learned never to say never at this point in my career. If you told me that I would've been playing the Country Music Awards, I would have said never."
