FRIDA star Mia Maestro is obsessed with scuba diving after taking lessons in the water sport for new deep-sea disaster film POSEIDON. The Argentine actress spent hours underwater in the upcoming remake and now she can't stay out of the ocean - or the bath. She explains, "Your body never gets used to being wet 12 hours a day for five months. When we were freezing the production put a hot tub in for us between scenes. "They gave us little bottles of water not to get too dehydrated. You get addicted to it. I would come back home and take a 40 minute bath which sounds crazy. "I decided to keep up with my scuba diving and swimming - you miss it after a while."
