Lindsay says she and Samantha have been together "...a very long time."

It's been clear for some time now that Lindsay Lohan and Samantha Ronson are a couple but they've never really said anything about it publicly. They finally did so this week in a real casual way.

Here is an account of how it happened, according to AfterEllen.com,

After months of refusing to comment on the public speculation about their relationship, actress Lindsay Lohan and DJ Samantha Ronson finally publicly confirmed their relationship in a L.A. radio call-in show last night, in a short, casual exchange confirming that they've been together "a very long time."

Lohan and Ronson called into the radio show Loveline last night to chat with DJ Ted Stryker about DJ AM's recent survival of a plane crash that killed four other passengers.

In wrapping up the conversation, Stryker casually asked Lindsay on air, "Now, you guys, you and Samantha have been going out for how long now? Like two years? One year? Five months? Two months?" Lohan responded, "A long...a very long time."

"I hope you guys stay together, you're a very lovely looking couple," Stryker added, to which Lindsay replied, "Thank you very much."
