'Melrose Place' sexpot Katie Cassidy loves to pig out on cookie dough!

"Melrose Place" sexpot Katie Cassidy is obsessed with the signature style of the show's costume designer, Emma Trask.

She admitted that her strong-shouldered Louis Verdad dress made her feel powerful at Sunday night's Hollywood Life Hollywood Style Awards, where Trask picked up an award for making MP the most stylish show on TV.

The sophisticated actress -- wearing a complex up do similar to January Jones' elegant braided bun in the Rome business trip "Mad Men" episode -- sheepishly admitted that her whole family puts on holiday talent shows that are fun, but sometimes embarrassing. 

"They all get up and sing or dance or do monologues," she says, laughing. "It's really different than most families."

But the most surprising revelation? 

She loves to pig out on cookie dough during the holidays. 

"It's amazing. I can eat, eat, eat."
