Fergie looked sophisticated in a yellow Ungaro dress at the 2013 Trevor Project Live event.
Her hubby Josh also dressed to impress in a dark suit, white shirt and grey tie as he posed by her side.
Actress Sarah Michelle Gellar looked sophisticated in a prom-style little black dress by Rebecca Taylor. The 36-year-old beauty's strapless number was embellished with silver jewels on the bodice to match her sparkly metallic heels and silver headband.
Nina Dobrev opted for an elegant sleeveless blue gown by Elie Saab, which featured a collar top and pleated chiffon skirt. To finish off the glamorous outfit Nina held a small metallic Rauwolf clutch bag and wore Rupert Sanderson heels.
Fellow actress Kat Graham went for a more risqué ensemble. The brunette beauty arrived wearing a low-cut black Versace jumpsuit and black and red Gio Diev heels. To not take attention away from her revealing number Kat wore no jewellery and instead focused on her make-up with nude lips and blue smoky eyes.
The Trevor Project, who put together the event, is the nation's leading provider of crisis intervention and suicide prevention services to lesbian, gay, bisexual, transgender and questioning youth.
