Lindsay Lohan is confirming what the world has already figured out. That she's been dating Samantha Ronson "a very long time."

Lohan was casual Monday night when she told the co-host of "Loveline" about the relationship. Ronson herself had been on the line with DJ Ted Stryker talking about her friendship with DJ AM and Travis Barker, who were critically burned in a plane crash.

Then, when Ronson put Lohan on the phone, Stryker asked "you guys, you and Samantha, have been going out for how long now? Like two years, one year, five months, two months?" Lohan laughed and answered "for a very long time."

Lohan and Ronson have been stuck like glue to each other for months but have never publicly confirmed their relationship.
