In several reports, the actress was considered so much more attractive that she was deemed "unrecognizable."
Lawrence took a break from filming the "Hunger Games" sequel, "Hunger Games: Catch a Fire," to attend the event with her co-stars Bradley Cooper and Robert DeNiro.
The 22-year-old, known for portraying the lead role Katniss Everdeen in one of this year's biggest box office blockbuster films, later attended the after party at Soho House in Canada in a gold Alexander McQueen dress.
"I call this my cracked dirt dress," she told Daily Mail.
Lawrence joined fellow actresses Kristen Stewart and Emma Watson at the exclusive members only club.
Watson, 22, attended the festival to promote her new film, "The Perks of Being a Wallflower," and Stewart first arrived in Toronto to attend the premiere of "On the Road" on Thursday, Sept. 6.
"They're just three girls having a quiet chat after a long day and an even longer night working" said Nick Jones, the private club's founder.
The Los Angeles Times described that "Silver Linings"' is about a man with a mental illness played by Bradley Cooper. His character suffers from bipolar disorder and has tendencies to attack people both physically and verbally. De Niro plays his father.
"Silver Linings" is the first film from director David O. Russell in two years. Russell directed "The Fighter" starring Christian Bale as a boxer addicted to crack cocaine. Bale won the Academy Awards for Best Supporting Actor and many other awards for his role in the critically acclaimed film.
Russell told Daily Mail that Lawrence "glows in every scene" if her new film.
"The Silver Linings Playbook" also stars Jacki Weaver and Chris Tucker and will arrive in theaters on Nov. 21.
The Toronto International Film Festival runs through Sept. 16.
