Latest Twist In Bristol Saga

Bristol Palin calls it quits with fiance Johnston: ANCHORAGE, Alaska — The on-again, off-again engagement between Bristol Palin and Levi Johnston is off _ again. The 19-year-old daughter of former Alaska Gov. Sarah Palin called off her wedding plans after Johnston told her he may have fathered a baby with another woman. Bristol Palin did not identify the woman when she gave a teary interview to People magazine to announce the breakup. A pregnant ex-girlfriend of Johnston has publicly denied he is the father. Palin said Johnston told her about the baby on July 14, the day the couple announced their re-engagement. Palin and the 20-year-old Johnston have a toddler son together, Tripp. Representatives for Palin and Johnston did not immediately return requests for comment Tuesday. But Johnston's attorney, Rex Butler, told The Washington Post he doubts the pair have permanently split. "These young folk have a lot of pressure on them right now," he said. "All you have to do is watch that show 'Bridezillas' _ it's on and off, on and off, depending on the pressures." Palin had said she didn't have her mother's full support over reconnecting with Johnston. She said both her mother _ the 2008 GOP vice presidential nominee _ and father Todd worried she would get hurt again. Palin said the "final straw" was when Johnston told her he was going to Hollywood to see a hunting show, but actually went there to star in a music video mocking her family. In the video being shot this month in Los Angeles, Johnston will play a lover whose romance is thwarted by his girlfriend's disapproving mother. The project is based on the song "After Love" by singer-songwriter Brittani Senser. "He's just obsessed with the limelight, and I got played," Palin told People.
