It's not time for a change after all! It's allegedly out with the new and in with the old for Hollywood heartthrob Ryan Reynolds. Just weeks after ending his brief romance with beauty Charlize Theron, the Change-Up star is reportedly romancing his ex-wife of one month, Scarlett Johansson. Although the ink is barely dry on their divorce papers, the cute couple is said to be bringing sexy back... with each other. Radaronline.com says that the two thespians are constantly in touch. In fact, a source tells Star magazine that the beauty, who was in a relationship with Sean Penn post-Reynolds, is giving her fingers a workout as she is constantly blowing up his phone since the two hit up their favorite Los Angeles hotspot for a secret rendezvous. Says the source, "She's been texting and calling him nonstop since the dinner." Ironically, the rumors come at a time when Reynolds has been linked to Theron, and his ex to Hangover 2 star Justin Bartha. Their potential reunion shouldn't come as much of a shock, especially to anyone who watched Reynolds' recent appearance on The View. The 34-year-old Hollywood hunk became emotional while discussing his failed marriage with Barbara Walters. He told the talk show host, "I'm not going to cry around you, Barbara. Don't even. Don't even. Okay, here it comes." Johansson and Reynolds supposedly split because the 25-year-old actress isn't ready to have a baby, while it's the exact opposite for Reynolds. The insider added, "Scarlett said her career is her baby. But Ryan's a family guy." Maybe the second time will be a charm for the talented twosome.
