Michael Lohan has insisted that the close relationship his daughter Lindsay has with Samantha Ronson is "is evident to anyone with half a brain."

Firecrotch and her gal pal were spotted in Cannes last week nuzzling necks, prompting rumours the two have embarked on a lesbian affair. The pair have also allegedly become engaged.

Speaking to Us magazine, Lilo’s Christian father says his 21-year old "is a big girl, and she can make her own life choices. Then it is between her and God."

"Just like the [topless] Marilyn Monroe spread, Linds is my daughter and there are just some things a father doesn't want to see or hear, regardless of whether they are true or false."

Lindsay’s mother Dina has denied claims that her daughter is a lesbian. Is Michael implying his ex-wife only has half a brain?
