Troubled GREY'S ANATOMY star Isaiah Washington is the odd choice to front a new public service announcement on behalf of the Gay + Lesbian Alliance Against Defamation (GLAAD). The actor met with gay community leaders earlier this year (07) after he came under fire for using a derogatory term against gay castmate T.R. Knight during an on-set spat last October (07). Washington has since undergone counselling for his homophobic outbursts and now aims to prove he's a changed man by starring in a new TV campaign.
