Brtiney Spears And Justin Timberlake Photo in Madonna's Sticky and Sweet Concert Tours

Both Britney Spears and Justin Timberlake made a "surprise" appearance in Madonna's Sticky and Sweet concert tour. Here are some snapshots



Britney looked good fully dressed. Baggy pants and nice clean shirt made her sexy and not-so-trying-hard. She sang "Human Nature" with Madonna. She looks much better than Madonna I think, not having to make such an effort



Justin Timberlake also made a "surprise" performance, singing alongside Madonna for their famous pop hit - "4 seconds"
