Ashlee Simpson sported a dramatic platinum blond pixie cut at LAX with Bronx yesterday. She spent the Summer sporting the ombre trend with her long locks and her husband Pete Wentz debuted her new 'do on Twitter earlier in the day — Bella wants to know, love it or hate it? She now shares the same hue as her towheaded son and bright-haired sister Jessica. Ashlee supported Jessica at last month's launch of her latest collections, and Pete rounded out the family affair as the event's DJ. Jess couldn't return the favor and be by Ashlee's side for her recent 26th birthday, since the older Simpson was overseas on a USO trip.
