Ashlee Simpson-Wentz celebrated her 25th birthday with Jess and her fiancé Pete Wentz at the Wet Republic Pool on Saturday in Las Vegas.

She looked positively smoking and trilby – and don’t forget this is mere months after the birth of her first child.

Jessica and Ashlee Simpson were snapped relaxing on a luxury yacht over the weekend watching Jessica’s beau Tony Romo play golf on the 17th hole of the Edgewood course from the lake during the American Century Championship.

Thousands of fans, some who waited almost 9 hours in line, came out to see the young performer.

Ken Paves, who has coiffed the Simpson sisters since Ashlee was barely 13, worked his magic on Ashlee Simpson over the weekend. After nearly two hours of washing, cutting, styling and repeating, the entrepreneurial hair stylist’s masterpiece was finally complete. We don’t see a difference in her hairstyle!

With her honey blonde extensions sewed on tight, the plasticized pop singer was all smiles as she made her merry little way back to her car.
