Katie Holmes stopped by The Late Show With David Letterman on Monday evening, and even before she slipped into a sparkly dress, she looked gorgeous!

The 35-year-old actress chatted about her upcoming projects, but what Dave really wanted to know was what she's doing for Thanksgiving later this month. Katie revealed that her mom is finally going to teach her how to cook a turkey, and that she's hosting her family. We're guessing ex-hubby Tom Cruise isn't invited...

"I'm very excited because I'm the baby of five, and I've been using that for a long time but this year I'm taking responsibility and my mother's going to teach me how to make a turkey," Katie said.

Dave asked the starlet if she was going to roast her turkey, to which she replied, "Well I don't know, is that what you do?" She's so clueless ... but so cute! Watch the rest of her interview below:
