Mark Ronson Approves of Sister's Romance With Lindsay Lohan

Mark Ronson approves of his sister's burgeoning relationship with Lindsay Lohan.

The super-producer reckons sister Samantha Ronson and the Mean Girls actress look great together.

Lohan and Ronson were spotted getting cozy together at the Cannes Film Festival last month. They were also recently spotted hanging out in LA with British pop singer Lily Allen.

And Mark -- who worked with Amy Winehouse on her smash hit Back to Black album -- says his younger sibling and Lindsay make a a great pairing.

"My sister and Lindsay make a cute couple, don’t they?" he said.

Neither Lindsay, 21, or openly gay Sam, 30, have confirmed they’re an item.

However, Lohan's dad, Michael, said their relationship is "is evident to anyone with half a brain."
