LOS ANGELES (AP) -- Lindsay Lohan has confirmed what the world has guessed: She's been dating Samantha Ronson "a very long time."

The 22-year-old actress casually told the co-host of the syndicated radio program "Loveline" on Monday that she's been dating the 31-year-old DJ. The pair have appeared in public and been photographed together for but have never publicly commented about the extent of their relationship.

"You guys, you and Samantha, have been going out for how long now?" DJ Ted Stryker asked. "Like two years, one year, five months, two months?"

"For a very long time," Lohan said after laughing.

Stryker interviewed Ronson while she took a break from DJing at TV Guide's Emmy afterparty Monday night in Los Angeles. Ronson had been discussing her friendship with DJ AM and Travis Barker, who are recovering from severe burns following a plane crash in South Carolina last weekend, before putting Lohan on the phone.

Lohan's publicist, Leslie Sloane-Zelnik, told The Associated Press on Monday that Lohan is not engaged to be married.
