Bristol Palin, Levi Johnston engaged - again

According to exclusive reports from US Weekly, Bristol Palin and Levi Johnston are engaged to be married.

Bristol, 19, and Johnston, 20, were thrust into the public eye during Bristol's pregnancy when her mother Sarah Palin, former governor of Alaska, was named the vice presidential nominee to John McCain's 2008 presidential bid.

They called off their previous engagement shortly after their son, Tripp, was born in 2008, but the relationship was reportedly rekindled three months ago during custody negotiations.

Bristol told Us, "When he left that night, we didn’t hug or kiss, but I was thinking how different it was. He texted me: 'I miss you. I love you. I want to be with you again' ... I was in shock."
