The model-turned-actor, who featured in cycles two and three of the US reality show, can be seen in Rockstar.
"Hey guys - just wanted to say hi… been so tired - I thought the hard work would end now that it's over but it's actually just beginning. Whoa," the star posted on Twitter on Monday.
Fakhri was finally eliminated from the programme after judge Tyra Banks felt that she was not committed to the industry.
The star acts opposite Ranbir Kapoor in the Imtiaz Ali-directed project.
Fakhri's identity as the lead in the film was deliberately played down before the movie released, following reports that she was in a relationship with Kapoor.
Rockstar is out now on general release.
