At Dodger Stadium last night in L.A., Britney Spears was reunited with Madonna (and Justin Timberlake, yes, the two did cross paths!) for her Sticky and Sweet tour. Greeting her with a kiss on the hand and a "Hi Britney," Madonna was joined onstage by Spears during her song "Human Nature." Spears looked great in black and white as she sang the last chorus of the song. And as for the reunion with Timblerlake, the two said a simple "hi" to each other.
