And Hilton has now agreed to change his ways in a bid to give his campaign more gravitas.
He tells gay star DeGeneres, "Over the last two weeks, I have been doing everything I can to bring awareness to the teen suicides and gay bullying.
"In doing so a lot of people have called me a hypocrite and a bully myself, and a big one. ... From now on I really want to be part of the solution and not part of the problem."
In the past Hilton has been embroiled in online feuds with Lily Allen and Miley Cyrus and was involved in a real-life altercation with pop star will.i.am after criticizing his Black Eyed Peas co-star Fergie on his blog.
