Adele says she's been so busy singing nursery rhymes to her new baby son that she doesn't "really remember what's cool and what's not".

Still, she was cool enough to add another Grammy to last year's six-award sweep when she won Sunday night for pop vocal performance for Set Fire to the Rain (Live).

She's set to perform her Golden Globe-winning song from the James Bond film Skyfall at the Oscars in a couple of weeks, and says she's been so busy she's had little time to work on her new album.

"I'm not very far along at all," Adele confessed backstage at the Grammy Awards.
