Things may be heating up between Scarlett Johansson and Sean Penn.
While the two have not confirmed a relationship, the two actors, who have been spotted together in recent months and both attended actress Reese Witherspoon's wedding in late March, are reportedly living together.
Spokespeople for the two had no immediate comment on the report. In February, a rep for Johansson denied the two were dating.
Johansson and Penn were photographed together again recently, this time jogging with actor Owen Wilson near Penn's Malibu home. The pictures, published on ABCNews.com, depicted Johansson sporting a bulge around her stomach area, spurring pregnancy rumors. Her spokesperson denied the actress is expecting a baby.
Ryan Reynolds, Johansson's husband of two years, filed for divorce in December 2010. The two married on Sept. 27, 2008 in Canada after dating for about a year. They have no children. Reynolds cited irreconcilable differences as the reason for the split, according to the legal papers.
Penn, meanwhile, became officially divorced from Robin Wright, his wife of 14 years in July 2010. The two have a 20-year-old daughter, Dylan, and a 17-year-old son, Hopper.
