In a brief post on her MySpace blog, the 22-year-old actress wrote: "We did NOT break up!"
Lohan asked several media outlets "AND every GOSSIP website" to get their stories straight.
The "Mean Girls" star also complained Monday that her friends had been e-mailing her to console her about the rumored breakup with the 31-year-old Ronson. The pair had confirmed their relationship last September.
Lohan's publicist, Leslie Sloane-Zelnik, didn't immediately respond to a message seeking comment.
What The El!?! Editorial:
Does anyone really care? I saw "I Know Who Killed Me" and it made me want to kill myself -- the acting was so bad. And I literally watched 5 minutes of "Georgia Rule" before I hit eject on the DVD and took it back to Blockbuster.
Lindsay is a non-factor in Hollywood. If she vanished the Hollywood sign would not fall off the hill. I think her window of opportunity for a real superstar career has closed, and if this relationship is over WHO CARES?
