Levi Johnston's feud with Sarah Palin was well documented.

We'll see if his own mother makes that look like child's play.

The Playgirl model’s mom, Sherry, and his sister, Mercede Johnston, are not pleased at the way in which they learned of Levi and Bristol's second engagement.

That would be via celebrity gossip publications ... naturally.

“You would think that a normal family would call you and say, ‘We’re getting married.’ We found out through the media, which is heartbreaking and rude,” Mercede, who recently started up an anti-Palin blog, told Inside Edition.

Hard to argue with that, MJ.

After first hearing about her son’s decision to walk down the aisle in a tabloid magazine, drug dealer Sherry even fears she won't be welcome at the nuptials.

“I would be absolutely devastated if I wasn’t invited to the wedding it would be the last straw. They should elope if they can’t have both the Johnstons and the Palins together. But don’t leave us out of it. That would kill me,” she says.

Speaking of the Sarah Palin, she must have been too busy making up words and comparing herself to Shakespeare, because she was out of the loop as well.

She said in a vapid statement about the news: "Bristol at 19 is now a young adult. We obviously want what's best for our children. Bristol believes in redemption and forgiveness to a degree most of us struggle to put in practice in our lives."

What do you think? Will it last?
