Hilary Duff: Kentucky Derby Prelude Party!

Hilary Duff stays classic in black during the Kentucky Derby Prelude Party at The London Hotel in Los Angeles on Thursday (January 13).

The 23-year-old singer/actress helped kick off the Kentucky Derby season, which officially begins this Saturday. Two early prep races will take place in California prior to that.

Last week, The Duffster tweeted, “Hello everybody! Just heading back to CA. Had the best trip even though I was playing nurse for poor mikey (husband Mike Comrie). He is recovering so well though!!”
