says her Golden Globe nomination was a "thrilling" moment in her normally blissful, domestic life.
"Usually the triumph of my day is everybody making it to the potty," she cracks in an interview with Matt Lauer on the Today
show scheduled to air Friday. "So yes, I think it's thrilling."
Asked if Roberts, who received a best supporting actress nod for Charlie Wilson's War,
feels "ho-hum" about yet another nomination to add to her roster of three past Globe wins and an Oscar, she says, "I didn't realize I had done that much. That's great. No, it's exciting."
Roberts, 40, also has high praise for her Wilson
costars, Tom Hanks and Philip Seymour Hoffman. "Both of them are great. Philip is – he just kind of blows my mind a little bit. …Tom is probably the most honest person on screen and off screen that I've ever spent time with acting wise, he's just amazing."
As for her family life, she says her 3-year-old twins with husband Danny Moder are "just starting to figure out Christmas and the specific holiday."
And what are the holiday traditions she's passing on to her three kids, including 6-month-old son Henry? "It's a good food holiday in our house. So, I think, you know, the baking we do, the cookies with the icing."
