ANCHORAGE, Alaska (AP) - Bristol Palin and Levi Johnston have called off their second engagement after he told her he may have fathered a baby with another girl.
The other girl was not identified, but a pregnant ex-girlfriend of Johnston has publicly denied he is the father.
Palin, the 19-year-old daughter of former Alaska Gov. Sarah Palin, told People magazine that Johnston told her about the baby on July 14, the day the couple had announced their engagement. Bristol Palin and Johnston have a toddler son together, Tripp.
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.
Palin had said that she didn't have her mother's full support over reconnecting with Johnston, 20. She said both her mother and father Todd worried that she would get hurt again.
Relations between the Palins and Johnston and his family have frequently been strained since the couple broke off their first engagement soon after their son was born in late December 2008.
Sarah Palin, the 2008 GOP vice presidential nominee, 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."
Representatives for Palin and Johnston did not immediately return requests for comment Tuesday.
