Mark Ronson has confirmed that his sister Samantha is dating Lindsay Lohan, by referring to them as a “cute couple”.

The pair has yet to publicly reveal their rumoured lesbian romance, despite reports of them kissing at the Cannes Film Festival last month.

On Monday, they ate out in Los Angeles together with singer Lily Allen, a friend of super-producer Mark who is now hinting the relationship is for real.

He says: "My sister and Lindsay make a cute couple, don't they?"

When will we hear about the lesbian affair straight from the lovebirds lips?
