Don't expect Lindsay Lohan to be at her estranged father Michael's upcoming wedding to former tabloid reporter (and Jon Gosselin ex) Kate Major.

"I'm gonna vomit!" she told after hearing the wedding news Tuesday. "I so didn't need that info ... Yuck!"

The actress, 23, and Michael -- who turns 50 Apr. 25 -- have recently engaged in a war of words.

She lashed out at him on Twitter for years of bad parenting; he is urging her to go back to rehab.
