Some of the biggest stars of TV, music and movies joined forces for a great cause last night -- as Lady Gaga, Fergie, Neil Patrick Harris, Zoe Saldana, Jane Lynch, Miley Cyrus and more attended a benefit for The Trevor Project.

Gaga was honored with the biggest award of the night, The Hero Award, for "being an inspiration to youth and increasing visibility and understanding of the lesbian, gay, bisexual, transgender and questioning (LGBTQ) community."

The Trevor Project is a leading organization in providing crisis intervention and suicide prevention for LGBTQ youth.

Performers at the event included NPH and partner David Burtka, Miley, Queen Latifah, LeAnn Rimes, Julianne Hough and more -- with appearances from the casts of "Modern Family" and "Glee," Zoe Saldana, Christina Applegate, Joe Manganiello, Ricki Lake, out stars Zachary Quinto and Amber Heard and many, many more.
