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 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. “He's just obsessed with the limelight, and I got played,” Palin told People. Sarah Palin told People that she hopes her daughter will “move forward in life with her same forgiving, gracious, optimistic spirit, but from henceforth she'll know to trust but verify.”
