Robert Pattinson attended the concert with Sia, an Australian indie rock singer, and both tried to remain incognito as they made their way into the Rose Bowl Stadium.
Whether Kristen Stewart's ex, 27, and his concert date, 37, are anything more than friends remains to be determined. As you'll recall, though, R.Pattz was snapped kissing a mystery brunette just last week in Toronto, and Sia isclearly a platinum blonde.
Jessica Alba and hubby Cash Warren came out to see Hov and J.T. in action, too. The actress and entrepreneur Instagrammed a clip of Jay performing "On to the Next One." She also shared a cute vid of her pal Kelly Sawyer and her husband, Jamie Patricof, rocking out in the audience.
Clearly even the stars among us get OMG levels of excited to see Jay and J.T. in action!
