The 49-year old won a Best Actress Oscar in 2003 for her role in "The Hours".
When Charlize Theron walked on stage to present an award with Shirley MacLaine, Kidman stole the moment in a totally weird way.
Nicole went on to say she sees hubby Keith taking that same approach with his music.
At least Nicole's clapping moment was not as odd as this Brendan Fraser freakout...
This beaded beige Armani Prive look is so fresh, as she paired it with diamond bracelets and ruby earrings.
However, it wasn't her nomination that made her the talk of the town last night but her clapping. She's lovely, talented, married to Keith Urban, and can rock a bold red lip and 119 carats of Harry Winston jewels on a red carpet better than anyone else we know.
Continuing her footloose night, during the show, both Nicole and husband Keith Urban appeared smitten when Justin Timberlake greeted them in the audience. The red lip is also killing it.
"He lives and breathes music and I think that's why when I talk about connection, I feel him connecting to his fans through that music and it's so lovely when it gets acknowledged in its way as well", she said sweetly.
However, Kidman experienced a bit of a problem when a strap of her dress broke on the way to the ceremony.
But she managed to overcome the emergency, The Daily Mail reports.
