Lindsay Lohan

Lindsay Lohan and her family will not be seeing her newly announced half sister at the family’s Thanksgiving feast according to Fox News. Lindsay reportedly has no desire to meet her half sister or develop a relationship with her. The new half sister is definately not going to be invited to Thanksgiving dinner.

Lindsay Lohan hit headlines last week when it was revealed that paternity tests proved her father Michael is also a father to a seventeen year-old Montana girl named Ashley Kauffman.

Lohan though is feeling completely indifferent to her newly revealed sister.

A source told FOX411’s Pop Tarts column:

“Lindsay isn’t upset, she doesn’t care, and seems to have no desire to meet Ashley.”

Lohan has since been asked about her sister in several interviews including Good Morning America. Lohan was on the show promoting her new Lifetime film Liz and Dick. She said on the show that she had no previous knowledge that she has a half sister.

Yet the source told Fox that Lindsay Lohan did know about the half-sister, especially for the last few months. Lohan’s mother Idna is reportedly very distraught over the news.

Ashley Kauffman was reportedly conceived during a relationship with Kristi Horn Kauffman while Michael was still married to Dina Lohan in the 90s, and was born between their daughter Ali, now 18, and son Cody, now 16.

Representatives for both Lindsay and her father denied to release any comments about Ashley but last week Michael Lohan told reporters he is “one hundred percent happy” with the paternity results, adding that “we’re all okay with it and will deal with it in the best way we can.”

Michael Lohan originally denied any type of extramarital children and had previously refused to pay any for of child support.

Do you think Lindsay Lohan should be a little kinder and invite her half-sister out for a Thanksgiving meal?
