Holly looked glam in her little red dress, which was teamed with long chandelier style earrings and heels. 

The reality star wore her long blonde hair down in large and loose cascading ringlets, a style which featured a slight side part. 

She brought out her brown eyes with mascara, and let her natural beauty shine through with a coat of pink blush. 

And adding a sparkling touch was Holly's bright gold nail polish.

Holly released her second memoir The Vegas Diaries on Tuesday.

The new book gives the inside story of her life as one of Playboy boss Hugh Hefner's Girls Next Door, this time focusing on their Las Vegas escapades rather than their lives at the Playboy Mansion in Los Angeles, as her first memoir Down the Rabbit Hole did. 

Both tell-alls dish about the things that E! couldn't show in the reality series that ran from 2005 to 2009.
