Charlize Theron and Sean Penn spent the New Year’s holiday together at his beachfront property in Oahu, Hawaii and reports suggest the two Oscar winners may be more than friends. The actress, 38, was on the island without her 2-year-old adopted son Jackson and was spotted sunbathing while Penn, 53, surfed on Tuesday, Dec. 31. They relaxed on the beach side by side and an eyewitness described the pair as "very close and comfortable together."
