Scarlett Johansson, 26, and Sean Penn, 50, made a pretty bold if not official statement about dating rumors, showing up together at Reese Witherspoon and Jim Toth's wedding on Saturday.
Johansson and Penn were among A-listers Renee Zellweger, Tobey Maquire and Robert Downey Jr. attending the wedding at Reese's ranch in Ojai, California.
"Scarlett is Jim's client, but no one, including the bride, knew she would have turned up with Sean Penn," said a friend of Scarlett's. "Turning up at a wedding with your boyfriend is definitely a huge statement, especially that wedding. What it's doing is announcing to the whole of Hollywood that they are serious."
Sean and Scarlett have been spotted getting cozy several times over the past few months, and took a daytrip down to Mexico earlier this month.
According to a friend of the actress, she is "head over heels in love with Sean."
"She normally tries to hide away from public attention," says the friend, "but when she's with Sean she doesn't care."
