They've got that glow! Kate Bosworth
and director beau Michael Polish
were all smiles as they stood, hand-in-hand, chatting with friends in the lobby of West Hollywood's Chateau Marmont
. Says an onlooker of the new couple: "It was clear Bosworth was smitten with him." Then it was out to the patio, where the duo chatted with some friends who were dining there. After a brief conversation, they returned inside to the lobby, where they sat on the couch with more friends and shared a smooch.
