Trevor Project 2011: Honoree Lady Gaga & More A-List Stars Hit Red Carpet [PHOTOS]

Lady Gaga was honored for her commitment and contributions to the LGBT community at The Trevor Project's 2011 Trevor Live event at The Hollywood Palladium Sunday.

The fete was to promote the organization's provision of crisis intervention and suicide prevention services for lesbian, gay, bisexual, transgender and questioning youth.

Gaga, an avid activist for the community, was presented with the Trevor 2020 Award by the family of Jamey Rodemeyer, a teenage from NY who committed suicide in mid-September after years of bullying and harassment due to his sexuality.

Our young people are at the center of a health crisis, and vocal leaders like Lady Gaga and technology leaders like Google Inc have stepped up to help change our culture, said David McFarland, Interim Executive Director and CEO of The Trevor Project. Our honorees are working with The Trevor Project to make a better today and a brighter tomorrow for youth. We are proud to honor Lady Gaga with the Trevor Hero Award and Google Inc with the Trevor 2020 award for their work to help young people express their true selves with pride.

Rodemeyer was a fan of Lady Gaga's and posted a video to the It Gets Better forum describing his troubles. However, the struggles proved too difficult for the young boy. After his death, Gaga publicly expressed her despair and heartache over the tragedy and reestablished her commit to fighting against bullying.

Other celebrities in attendance Sunday included Josh Duhamel & Fergie; LeAnn Rimes and Eddie Cibrian; Zac Efron; Michelle Pfeiffer; Glee actors Chris Colfer, Darren Criss, Dianna Agron, Harry Shum Jr. and Amber Riley; Zoe Saldana; Julianne Hough; and Star Trek actor Zachary Quinto, reports RadarOnline.com.

Not only was the red carpet a huge hit, but the show included incredible performances by many of the attendees.

Miley Cyrus performed The Climb. Neil Patrick Harris and partner David Burtka sang Baby You're The Top. Darren Criss sang It's Not Unusual. Mary J. Blige belted out a rendition of Bridge Over Troubled Water. And actress/singer Queen Latifah crooned Have Yourself a Merry Little Christmas in tune with the holiday season.

Over the weekend, Lady Gaga underlined her dedication to the LGBT community. After a video of young Jonah Mowry, who is a bullied homosexual youth, describing his pain and perseverance in the face of sorrow went viral, Gaga tweeted to the boy. She expressed her support with a post: Thank you Jonah for being brave enough to share your story + showing us strength. You matter to millions. #TellYourStory #EndBullying.

The Trevor Project was founded by writer James Lecesne, director/producer Peggy Rajski and producer Randy Stone. These three individuals were behind the 1994 Academy Award-winning short film, Trevor, a comedy/drama about a homosexual 13-year-old boy who attempts to end his life after being rejected by family and friends. The Trevor Project provides 24-hour-a-day, 7-day-a-week counseling for youth in crisis.
