New couple Kate Mara and Justin Long are getting more serious. The cute pair was seen on a holiday getaway in the Bahamas. Spies say they were “holding hands and being romantic at Nobu” on Paradise Island. The lovebirds were also spotted last month on a date in the East Village to celebrate Long’s birthday. He was previously in an on-and-off relationship with Drew Barrymore, who just tied the knot. Mara was linked with younger sister Rooney’s “The Social Network” co-star Max Minghella.
