Britney Spears britmadonna.jpgBritney has arrived at Dodger's Stadium, y'all -- the site of Madonna's Sticky & Sweet concert date tonight ... Does it mean the rumors are true? Will Brit perform? Will Justin join the reigning pop queen and pop princess on stage?

Or could Britney just be going to check out one of her favorite performers ... from a box seat?

But why would she arrive so early???

X17 will be inside the concert and we'll be bringing you live updates on X17online.com so stay tuned!
