By Eileen Reslen. The Oscar-winning actress and the actor-director were photographed Monday enjoying a day at the beach. Larson fluttered along the shore in a one-piece swimsuit covered in a multi-colored butterfly print by Cover Swim — showing off her fit physique. The actor was photographed with a huge smile plastered on his face, carrying a purple inflatable pool float to go into the ocean for a dip. Larson and Allan-Blitz have been dating since and went public with their relationship in February at the Academy Awards. The couple is normally very private about their relationship, but Allan-Blitz recently gave a small glimpse into their lives together via Instagram.
