Poor Kathy Griffin. Her future baby daddy is off the market.

In a surprising move, Sarah Palin's daughter Bristol is engaged to her ex Levi Johnston, Breaking Celebrity News can report.

"We got engaged two weeks ago," Bristol, 19, tells the new issue of Us Weekly which first broke the story. "It felt right, even though we don't have the approval of our parents."

Bristol and Levi had been briefly engaged in the past, but called it off only two weeks after the birth of their son Tripp back in December of 2008.

And judging from Bristol's cyptic comments to the magazine, it looks like mom Sarah may not have known about the surprise engagement.

"It is intimidating and scary just to think about what her reaction is going to be. Hopefully she will jump on board," Bristol told Us Weekly.

The couple says they reconnected three months ago while working out a custody plan for their 18-month-old son, Tripp.

"I really thought we were over," Levi, 20, says. "So when I went, I had no hope. I think we both just started talking - and then we took Tripp for a walk."

Bristol adds, "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."
