Lindsay Lohan has banned her father from attending a party she is throwing with girlfriend Samantha Ronson.

The 22 year-old actress and her DJing GF are hosting a party for a group of their closest friends and family at the Peninsula Hotel in Hollywood on August 8. Sam and Lindsay want to thank the people who have been the most supportive of their somewhat unorthodox relationship; and that’s precisely why Bible-thumpin’ Papa Michael Lohan is not on the guest list, a spywitness eagerly dished to the Daily Sport.

Lindsay is petrified her Pop will create a stir because he doesn’t approve of his daughter’s lesbian love affair.

“Michael thinks Lindsay is just going through another phase and that she will end up getting hurt. He thinks it’s embarrassing.”

Lindsay has hired additional security to ensure doesn’t enter the party.
