She’s been a staple in the teen/tween entertainment diet ever since her days on “Lizzie McGuire.” And last night Hilary Duff helped say goodbye to another mainstay of young people all over the world - MTV’s Total Request Live.

The “So Yesterday” singer stopped by the “Total Finale Live” shindig at MTV’s Times Square Studios, joining the likes of Taylor Swift, Justin Timberlake, Beyonce, and Mr. TRL himself, Carson Daly.

And of course, Miss Duff stole the show with her sexy ensemble, sporting a black belted minidress complete with a long black sheer see-through overlay and black heels.

Of her new single “Reach Out” (from her greatest hits album), Hilary told press, “It’s different for me. It’s a little dancey, and there’s a rapper named Prophet who’s on it who’s really cool and kinda fresh.”
