Ricky Martin and other stars supporting bullied gay youths by 'going purple'

Ricky Martin, Cyndi Lauper and Julianne Moore are among the celebrities who have pledged to "go purple" on Thursday to show their support for bullied gay youths.

Martin will don all purple for a new photo on his Twitter page, while Lauper, Moore and stars like Chaz Bono and actresses Mia Farrow and Jamie Pressley have opted to wear purple as part of Spirit Day.

Meanwhile, MTV bosses are turning the network's iconic on-air logo purple for the day. This is only the second time in MTV's 30-year history that they have changed the logo for a cause.

It was also reported this week that actor Zachary Quinto, best known for playing Spock in the 2009 movie reboot of Star Trek, decided to go public with his sexuality after a gay teen committed suicide.
