But the other three aside, this rebound actually sounds the most believable!
Scarlett, 26, and Sean, 50, are both freshly divorced (Sean ended his marriage of 14 years recently) and according to Us Magazine they're totally doing it.
"Their first hook-up was in Scarlett's Bungalow," an insider told the mag.
Apparently the pair began their fling in January when Scarlett was in LA to film We Bought a Zoo with Matt Damon. She approached Sean because she was interested in helping out in earthquake-ravaged Haiti.
“Scarlett first reached out to Sean when she was planning to visit Haiti with Oxfam," says the source. "She knew Sean was living there in a tent and turned to him for advice."
Obviously the next logical step was for them to hook up!
"Scarlett's smitten with him," adds the source.
