Lindsay & Ali Lohan are Beach Babes

Sisters Lindsay and Ali Lohan show off their curves and get wet and wild during some surfing lessons in Hawaii on Thursday (April 30).

Lindsay, 22, and Ali, 15, both then headed to the spa at the Grand Wailea Resort for some pampering.

LiLo has spent the week in bikinis on the beaches of Maui, Hawaii, getting away from the recent blow-up with Samantha Ronson.
