may have reflected '20s-style Hollywood glamour in the stunning beaded gown she wore to the 2004 Oscars, when she won as Best Actress for Monster
– but this year she plans on something completely different.
At least that's what the South Africa-born actress, 32, revealed Friday at the Dublin International Film Festival, where her director and actor boyfriend Stuart Townsend's new movie, Battle in Seattle
, premiered, reports Britain's Press Association.
"We are not going. I don't think you go to those kind of award shows unless you are nominated," says Theron of the Feb. 24 event at the Kodak Theatre.
"I think it's a special thing if you get a nomination, or your film does. Then you go. But we don't have any nominations or anything like that in the house, so we sit in our jammies and watch it on the couch."
Something else Theron isn't rushing to dress formally for: her and Townsend's wedding.
"I have no plans on getting married," she declared.
