Darren Criss & Katy Perry’s ‘Teenage Dream’ Duet At Trevor Project Event

Tons of celebrities including Joe Manganiello, Paul Wesley, Anna Kendrick, Josh Duhamel and Jessica Alba stepped out for last night’s Trevor Project benefit at the Hollywood Palladium. The highlight of the night had to be Darren Criss being joined onstage by Katy Perry for a duet of her song “Teenage Dream” (via Towleroad).

Actress Jane Lynch presented Kathy Griffin (keeping her clothes on) with an award after the comedienne pledged the profits from her upcoming stand-up show to the crisis hotline for gay youngsters.

Queen Latifah also performed, while married couple Taye Diggs and Idina Menzel covered “Ebony and Ivory,” and Neil Patrick Harris and James Marsden sang together live – sealing their track with a kiss.

Plus Emma Stone debuted her new blonde hairdo for her upcoming role as Gwen Stacy for the Spider Man movie.
