We’re sure Cheech Marin, 62, is still high from his February 17th engagement to his longtime girlfriend, Natasha Rubin. People reports the Cheech & Chong actor proposed to Rubin, a classical pianist, during dinner at the elegant L.A. restaurant Giorgio Baldi. “The couple are thrilled and looking forward to sharing their special day with close friends and family," says his rep. Marin and Rubin will marry in his Malibu home this summer.
