Indie cosmetics line Nyx Professional Makeup celebrates its Decade+1 year with a star-studded beauty event held at The Roosevelt Hotel in Hollywood on Tuesday night (May 18).

On hand for an evening of fun and fashion? Jessica Lowndes, Carmen Electra and American Idol alum Katharine McPhee. While Carmen sparkled in a long-sleeved LBD, Katherine and Jessica opted for whimsical ruffles to make their style statement.
