Lindsay Lohan wants nothing to do with her newly discovered 17-year-old sister, according to TMZ.

According to Lohan's friends, the actress is 100 percent done with the "circus" that is her father Michael Lohan and doesn't want to meet her half-sister Ashley.

That's right. She has her own circus to manage.

Michael Lohan took a DNA test on national TV to determine whether he fathered Ashley in 1995 with a former mistress, and the results came back positive. The announcement was made last week.

TMZ reported that Lindsay Lohan was aware of the paternity dispute, since it's been going back and forth for years, but didn't know her father took a DNA test until the story went public.

Lohan hasn't communicated with her dad since he leaked the recorded phone call during her fight with her mother Dina last month. She no longer wants anything to do with him. And she tells friends her life is better without his drama.

Come on, Lindsay, lighten up. It happens to all of us.

Lohan supposedly has no hard feeling toward Ashley, but finds the entire situation "disgusting," especially since her father had the affair while still married to her mom.

Michael Lohan told TMZ, "I am sorry to hear Lindsay feels that way. I met Ashley and she is a good kid. But we all have our choices to make in life, as well as our own prerogatives. Who knows, maybe someday things will change. Regardless, I want the best for all my kids."
