Celebrity Charlize Theron and Sean Penn Are Not Engaged 'Yet,' Says Source Despite reports, the actors aren't quite ready to make their relationship official By Julie Jordan Published on April 14, 2014 11:30 AM Share Tweet Pin Email Trending Videos Photo: Jason Kempin/Getty Sean Penn and Charlize Theron are getting more and more serious about each other, but recent reports that the actor popped the question are false. Friends of the couple “wouldn’t be surprised” by a proposal, says the insider. “But she’s not engaged – yet.” The two took their romance public in January at Penn’s third annual Help Haiti Home gala after appearing to be more than just friends during a holiday trip to Penn’s beachfront home in Oahu, Hawaii, where the pair celebrated the New Year together. The Oscar winners then spent Valentine’s Day weekend together in Cabo San Lucas. “They were inseparable,” an eyewitness told PEOPLE of their Mexican vacation. “They held hands everywhere they went.” Penn, 53, is also planning to direct Theron, 38, in the love story, The Last Face, costarring Javier Bardem, which will likely shoot in Africa. Reps for the couple have not commented.
