It's official, folks:

Michael Lohan is engaged to Erin Muller.

Lindsay's ex-con of a father had pretty much made this announcement last month - but he's now announcing it to the world, via Star Magazine (the bigger gossip tabloids, like most of the world, obviously don't care very much).

“We’re thrilled to announce our engagement. We can’t wait to start our life together as a married couple,” the couple, who have been dating for over a year, said in a statement. “We haven’t set a date yet, but we hope it will be a family affair.”

And we hope tear gas is dropped onto said family affair.
