Lindsay Lohan held a party at Ultra Supper Club as part of the 2008 Toronto International Film Festival on Friday night (September 12) in Toronto, Canada.

Lindsay’s girlfriend Samantha Ronson took over the deejaying duties for the night (not pictured).

In related news, Michael and Dina Lohan are both denying that a ring Lindsay has been wearing is an engagement ring. Michael tells E! “It’s all BS, it’s not true.” While a source close to Dina says “she said it’s just one of Lindsay’s cocktail rings, nothing more.”

A friend of the actress adds that “it’s like her own personal joke these days, she slips a ring on that finger, then goes to a party and watches the rumors start to roll. It amuses her.”
