Markus Klinko and Indrani were left waiting for the Mean Girls star when she was "majorly late" for a session, which was being filmed for the couple's U.S. reality TV show Double Exposure - but Lohan insists the drama was enhanced for TV.
The actress took to Twitter.com to tell fans she was "set up".
She wrote, "(It) sucks when 'friends' use you (in this case for ratings) even if they're lying... I was given the wrong call time - now I know on purpose... it was a set-up. I don't appreciate being used for press, and I'm sure others would agree! Photo shoot for Indrani and Markus... So that's bulls**t too.... Thank goodness for Twitter! The truth can be stated!"
But the photo duo insists it's Lohan who is lying.
Klinko tells Eonline.com, "We just don't understand why she said that."
Indrani adds, "I was really upset by her take on things. It was very upsetting to feel, like, she's saying that we lied, which we absolutely did not at all. Quite the contrary. We hung in there for her and I feel like it would be nice if she appreciated that a little bit because we've been there for her completely."
