Lohan’s dad Michael, is a good Christian which means he won’t play the proud father or walk her down the aisle if she’s marrying Sam.

“I haven’t heard anything (about an upcoming wedding) from Lindsay, but if she was marrying Sam, I don’t think she’d ask me to walk her down the aisle,” says Michael. “She knows about my (Christian) faith … she just wouldn’t ask.”
That’s not to say that he doesn’t support Lindsay and a possible relationship with Ronson, he just supports her in more indirect ways.
“I want her to be happy and healthy and stay on the right path,” he says. “If I discuss (her relationship), I say that I want her to be happy.”
