Bristol Palin and Levi Johnston engaged!

Bristol Palin and Levi Johnston reveal exclusively in the new Us Weekly that they are getting married. And, they tell the mag, former vice presidential candidate Sarah Palin has been kept in the dark about their plans … until now. “We got engaged two weeks ago,” Bristol, 19, tells Us Weekly. “It felt right, even though we don’t have the approval of our parents.” Bristol and Levi, 20 — who famously called off their previous engagement two weeks after welcoming son Tripp in December 2008 — tell Us Weekly they reconnected three months ago while working out a custody plan for their 18-month-old son. Now comes the hard part: Getting the blessing of Sarah Palin, who has made no secret of her feelings for Levi. Says Bristol, “It is intimidating and scary just to think about what her reaction is going to be. Hopefully she will jump on board.”
