Lindsay Lohan canceled a Toronto International Film Festival appearance scheduled for Sunday, a day after the actress or someone with access to her Instagram account posted what seemed like an incoherent message.

In an apparent reference to the Sept. 11, 2001, terrorist attacks on the World Trade Center, Lohan, 29, wrote, "They always come back. I love you NYC. they always come back. I love you NYC . . . Someone I was with the night before several towers fell, it felt like not a curse, but more like a spell. . What we think in America is not always clear, we don't have PETA commercials / you just kill deer. . . . with this being said, I'm a girl with a reputation mislead . . . Like a diamond in the rough, you, now, for 25 years have seen me on TV and screen. . So i am programmed to stand tough."

The message --- which accompanies what appears to be a fashion-shoot portrait of Lohan in an outfit she also wears in an Instagram image posted Sunday --- also refers to Michael Jackson: "#godblesstheworld #michaeljackson #rip miss you as my real only private friend. For you: god, for all hurts and wrongs, please let me forgive, Allah please let me be forgiven, and all forgive themselves. Please and thank you."

Tweaking gossip websites Lohan, originally of Cold Spring Harbor and Merrick, wrote, "Black or white -- in life, rather than love we create a fight of an ideal situation of an unexceptional, yet unacceptable future that @TMZ @Eonline @HarveylevinTMZ & #harveyweinstein . . couldn't and wouldn't even care to describe any thought of the people we forget to help when a franchise film comes out and, If money means more than freedom -- than [sic] stay in California."

Finally, she writes, "If helping others is a passion, talk to angelina jolie . . . If you want to be a brilliant actress, work wth [sic] Meryl Streep . . . at the end of the day -- republican or democrats -- BE HERE NOW @oprah and live with integrity. Or go to sleep. The most beautiful life comes cheap. Stop fighting and using artists for distractions. It's boring . . . #UnitedNations."

The Hollywood Reporter said Saturday that the "Mean Girls" star backed out at the last minute from attending a party in Toronto to help promote her next film, "Inconceivable." The magazine speculated the reason might have been her criminal record, which would have made it difficult for the actress to enter Canada under that nation's laws.
