Tonight is the season finale of 'The Glee Project' and the four remaining contestants--Damian McGinty, Samuel Larsen, Alex Newell and Lindsay Pearce--have one last chance to prove themselves for a role on the hit television show 'Glee.'

A surprise guest from 'Glee' is supposed to mentor the group on their final number, and all of the contestants return to sing Pink's 'Raise Your Glass.'

Earlier this week, it was speculated that Irish contestant Damian McGinty was accidentally revealed to be the winner when he was seen in 'Glee: the 3D Concert Movie.' I guess tonight we'll know for sure!

The finale airs tonight on Oxygen.
