Sean Penn and Charlize Theron dating relationship seems to be getting serious as the "Milk" actor took the "Prometheus" star and her mother to watch the show of comedienne Chelsea Handler on Saturday.

In a series of snaps published on MailOnline, Sean Penn and Charlize Theron were seen going into The Forum in Inglewood, L.A. along with her mother, Gerda, and another unidentified woman who was supposedly a friend of Gerda.

Sean Penn looked very casual in his khaki jacket and gray pants, and quite small compared to his high-heeled girlfriend, who rocked a checkered sweater and tight slacks along with peep-toe heels.

On Easter, paparazzi spotted Sean Penn and Charlize Theron dating at a Dodger Baseball game in L.A. along with her son Jackson, amid reports that the "Milk" star's ex wife Robin Wright was livid about casting the "Prometheus" star in the new film "The Last Face."

Fans attending the baseball game between the Dodgers and Arizona Diamondbacks got a little extra treat seeing Sean Penn and Charlize Theron dating with son Jackson.

Rumors of Sean Penn and Charlize Theron dating each other surfaced last year but it wasn't until recently that they confirmed the reports. The two have been seen doing ordinary things that married couples do, prompting reports that they are already living together.

According to the South African Sun-Times, the couple has been spotted shopping for an engagement ring while they were in the country filming "The Last Face," which earned the ire of Robin Wright after the "Prometheus" star was cast in the film.

Sources close to the couple told Page Six that Robin Wright has been working for years for the project to push through, only to see her ex hand it over to the "Prometheus" star.

"This is obviously a vindictive move against his ex-wife, for whom 'The Last Face' was a labor of love," a source told the publication.
