Britney Spears made an appearance at the end of Madonna’s performance of ‘Human Nature’ at Dodger Stadium in Los Angeles on Thursday (November 6) on the latest stop of the Material Girl’s Sticky & Sweet tour. Britney sang along for a bit and Madonna gave her a twirl before Spears exited the stage and she began performing ’4 Minutes’. That prompted the emergence moments later of Britney’s ex Justin Timberlake. Watch both moments below.
