Lea Michele, Chris Colfer, Cory Monteith and the rest of the 'Glee' cast kicked off their second annual summer tour this weekend, rocking the sold-out Staples Center in Los Angeles, a far bigger venue than the New Directions kids played last summer.

Seen here in a uniform of blue jeans, red tops and white vests, the cast was joined on stage by second-season breakout star Darren Criss, in full Warbler uniform. He brought the Warbler boys along for their hit rendition of Katy Perry's 'Teenage Dream' and Pink's 'Raise Your Glass.'

Gleeks also heard the main cast sing their covers of Lady Gaga's 'Born This Way' and Britney Spears' 'Slave 4 U,' and Michele reportedly brought down the house with her rousing versions of 'Don't Rain on My Parade' and 'Firework.'
