Delta Goodrem, Jennifer Hawkins at 2012 Crown Oaks Day

The celebrity set are back at Flemington Racecourse for Crown Oaks Day today, after launching the event at a fancy lunch yesterday. Myer ambassador Jennifer Hawkins looked divine in a floral headpiece by Flowers by Fleur, while fellow Myer ambassador Rebecca Judd wore Melissa Jackson millinery. Both celebrity stunners wore their hair in loose, beachy waves, and kept their nails relatively neutral — a huge trend for Spring. Delta Goodrem and Mischa Barton both went for bold lip looks at yesterday's luncheon, Delta for one proving the vampy lip need not be saved for Winter.
