(1 of 7) Celebrities at the DerbyPosh surroundings. Elegant appetizers. Fancy frocks. Extravagant accessories. And lots of sweet Southern hospitality. Kentucky was filled with classy ladies and debonair gents hobnobbing at the season’s most anticipated event: the Derby. Here Glam shows the chicest celebrities (and their hautest hats) at the 2008 horse race! Adrian Grenier and Isabel Lucas Grenier looks gorgeous and dashing as ever in a light and breezy white sports jacket. His better half is fun and flirty in a bright graphic mini-dress. Her simple black hat and bold red lips complement the look.
