Are Lindsay & Samantha Dunzo?

Say it isn't so!

Sources close to Lindsay Lohan say the actress and girlfriend Samantha Ronson broke up on Friday -- and that Sam had the locks changed on their house!

"This time, Sam means it," the source said of the split.

UsMagazine.com is reporting that the girls had a big fight at a party for Sam's sister, fashion-designer Charlotte Ronson, at West Hollywood's Bar Marmont.

"[Sam] told security to look out for Lindsay and block her from getting in," an insider blabbed. "Lindsay, of course...booked a room at [the hotel] Chateau and fully intended to crash the party and make a scene."

When Lindsay finally gave up trying to get in, she wrote on Twitter, "So-you win, you broke my heart. now go away. i loved you."

But when asked about the breakup via email, LiLo denied any trouble in paradise. "Oy vey. lol. Not true. hahahaha," she told the mag.

Lindsay Lohan is SUCH a drama queen. I can't really take her anymore -- I don't know how Sam does.

Update: Linds finally admitted to the split, telling E! News, "We are taking a brief break so I can focus on myself."
