Chris Brown busy writing songs for Britney Spears

Brown, who won best male video for "With You," wrote, "Disturbia," the song his rumored girlfriend Rihanna performed to open Sunday's show. The 19-year-old singer-songwriter is also crafting tunes Spears may record, he said.

"I actually wrote a couple songs for her now," Brown said, noting that Spears hadn't yet heard the new songs.

"We're on the same label, so all the executives heard the records and they love the records, so hopefully she'll cut it," he said. "But if she doesn't, oh well, we'll go back in the studio and still do some more records for her."

An in-demand collaborator, Brown appears on upcoming tracks by Nas and Ludacris.
