With Spirit Day 2011 exactly one day away, millions of Americans are gearing up to show their support for LGBT youth everywhere by wearing purple. On Thursday, October 20, these millions will be joined by a number of media outlets, corporations, celebrities and organizations—local, national and faith-based—that have taken the pledge to go purple.

MTV will show its spirit by boasting purple across the network in a number of ways. The iconic channel has committed to turning its on-air logo purple as well its Facebook, Twitter, MTV.com and MTV Act logos. The on-air logos and the online logos for MTV2, mtvU, MTV Hits, MTV Jams and RateMyProfessors.com will also turn purple. Spirit Day marks just the second time in the network's 30 year history that MTV will change the color of its on-air logo in support of a cause. Additionally, the network has also decided to think "really big" with its support by lighting MTV 44 and ½, the jumbotron in Times Square, purple for the day.

Celebrities from MTV shows will also show support by wearing purple. Celebrity talent includes: Sammi Giancola (Jersey Shore), Vinny Guadagnino (Jersey Shore), Farrah Abraham (Teen Mom), Tyler Baltierra (Teen Mom), Maci Bookout (Teen Mom), Catelynn Lowell (Teen Mom), Mike C. Manning (Real World D.C.), Jillian Rose Reed (Awkward.), Nikki Deloach (Awkward.), Matthew Fahey (Awkward.), Greer Grammer (Awkward.), Jessica Lu (Awkward.), Desi Lydic (Awkward.) and Beau Mirchoff (Awkward.) as well as Matt Pinfield, Charlamagne and DJ Envy from MTV2.

MTV and GLAAD recently partnered on MTV’s anti-bullying campaign, “A THIN LINE,” which empowers America’s youth to draw their own line between digital use and digital abuse. GLAAD is excited to extend thanks to MTV and all its other media partners for pledging to go purple in support of LGBT youth.
