Keith Urban's musical performance on ABC's Jimmy Kimmel Live Sunday night helped lead the show to its third-highest ratings ever. The post-Oscar broadcast came in only behind Jimmy's two previous post-Super Bowl shows. Keith wasn't actually in the U.S. when the show was broadcast, though. According to Sydney, Australia's Daily Telegraph, Keith and wife Nicole Kidman were spotted in Sydney on Sunday for Nicole's mom Janelle's 70th birthday party.
