MICHELLE PFEIFFER CRASHES TO THE GROUND

Michelle Pfeiffer’s shapely butt bounced on the pavement in a star wipeout — on skates! Meeting girlfriends for a rollerblading excursion at LA’s Oceanside playground Marina Del Rey, the “I Am Sam” star bought a new pair of skates at Sport Chalet, strapped them on and … CRASH! Her cute keister kissed concrete. Instantly, a dozen male bystanders rushed over, helped her up — and asked if they could assist in ANY way! Michelle just smiled and skated off with the girls.
