After a bitter public separation, Bristol Palin and Levi Johnston have reconnected and are getting married.

And while the two say they couldn’t be happier, they haven’t told Bristol’s mom, former vice presidential candidate Sarah Palin.

Bristol Palin tells the magazine that she finds the idea of telling her mother about her engagement “intimidating and scary.” But with the cover of Us announcing the news, we’re going to go ahead and say the cat is out of the bag.

“We got engaged,” Bristol, 19, told the mag. “It felt right even though we don’t have the approval of our parents.”

Her parents issued this statement Wednesday evening: “Bristol, at 19, is now a young adult.  As parents we obviously want what is best for our children, but Bristol is ultimately in charge of determining what is best for her and her beautiful son.

“Bristol believes in redemption and forgiveness to a degree most of us struggle to put in practice in our daily lives,” the statement continues. “We pray that, as a couple, Bristol and Levi’s relationship matures into one that will allow Tripp to grow up graced with two loving parents in his life.”

The couple has an 18-month-old son together named Tripp. They say they reconnected working out a custody agreement for him after calling off their engagement in December of 2008.

“I really thought we were over,” Johnston, 20, told Us. “So when I went, I had no hope. I think we both just started talking — and then we took Tripp for a walk.”

Bristol was just as surprised at Johnston’s turnaround as the rest of the world apparently, telling the mag she was “in shock” when he texted her to say “’I miss you. I love you. I want to be with you again.”

Johnston recently acknowledged telling lies about the Palin family after he and Bristol broke up last year. He says he has apologized to them.
