She has finally made a movie that’s being warmly received by critics and fashion commentators will also be giving Jennifer Aniston full marks for her glamorous appearance at the Toronto International Film Festival premiere of Life of Crime.

The 44-year-old actress looked ravishing in a blue dress which she paired with nude heels as she stepped out to promote her latest film on Saturday and Jennifer’s huge smile indicated she may have been reading her own reviews.

Or maybe it was her handsome date, fiance Justin Theroux, who was responsible for her good mood. The gorgeous couple cosied up at the cocktail reception for the movie presented by PANDORA Jewelry at Hudson Kitchen.

Jennifer put her toned arms on display in the plunging Vivienne Westwood strapless number, which showed off her impressive cleavage but kept her legs mostly covered in the draped dress.

She wisely kept her jewellery minimal, pairing large statement earrings from Fred Leighton with her impressive engagement ring from fiancé Justin Theroux and her famous locks flowed freely over her shoulders

The film is based on Emore Leonard's 1978 novel, and director Daniel Schechter commented about Aniston: 'It's the best work she's ever done and she'll blow people away. I don't think people will see it coming, she's so talented and I was crying while watching it.'

The movie – which also stars Tim Robbins and rapper Mos Def - received the honour of closing the prestigious film festival, an indication of how highly it is thought of by organisers. 

Earlier in the day, Jennifer, looking as youthful as ever, put in a chic appearance as she attended a press conference to promote the film.

And perhaps the star was in 'serious actress' mode as she opted for a simple black dress and matching strappy heels. 

However, the glamorous actress - who is a dedicated fan of Pilates - showed off her impressively toned legs.
