Lindsay Lohan says her father's engagement makes her sick.

The actress - who is estranged from Michael Lohan - admits she was less-than-pleased when she heard her dad is planning to marry journalist Kate Major.

She told "I'm gonna vomit! I so didn't need that info... Yuck!"

Kate, 27, and Michael, 49, broke the news of their engagement yesterday (06.04.10) and are hoping to marry before the end of the year.

Former Star magazine reporter Kate said: "I'm ecstatic. I'm very happy. Michael and I have known each other for four years, and it's meant to be.

"Michael went down with me to Florida for Easter, to meet my father to ask his permission, and my father gave his blessing.

"I've already talked to some of the bridesmaids, and it will probably be in New York, probably at the end of this year."

Michael was previously married to Dina Sullivan - Lindsay's mother - but the pair divorced in 2007.

As well as Lindsay, Michael and Dina have three other children, Michael Douglas, 22, Ali, 16 and Dakota, 13.
