Mum-to-be Jennifer Garner glowed as she took to the red carpet in Toronto.

Dressed in a spaghetti strap cocktail dress which draped across her bump, the 38-year-old mother of two looked serene as she promoted new film Butter at the film festival.

But protective of her growing tummy, the six months pregnant star kept a hand over it at all times.

Co-star Olivia Wilde, 26, could not have looked more angelic as she graced the red carpet in a flowing floor length Greek goddess style dress with light pleating and encrusted with gold embellishment around the neckline and cuffs.

She accessoried the vintage style dress with a shiny gold clutch but left out jewellery - simply allowing the bejewelled dress to speak for itself.

She also chose to keep her hair and make up simple, wearing her hair up in a simple bun and donning a fresh-faced but glowing make up look.

The film, a comedy, follows the story of a young adopted mid-western girl who discovers she has a talent for butter carving.

She then finds herself competing against an ambitious local woman in the towns annual contest.

It is just one of many roles Olivia has played this year after embarking on almost a dozen movie projects as well as her role on FOX's hit TV show House MD.

One of the films, which is currently in pre-production, will see her portray the famous sixties adult film star Linda Lovelace.

Olivia was joined on the carpet at the première by her co-stars in the film Ashley Greene, Jennifer Garner and Alicia Silverstone.

All three ladies, like Olivia, chose to add a touch of sparkle to their outfits.

Jennifer, 38, who is six months pregnant with her third child, looked radiant in a blush coloured cocktail dress with silver sequins.

Despite her growing baby bump, Jennifer paired the pretty gown with towering platform peep-toe stilettos.

Ashley, 24, looked conservative in a white and silver shift dress which she elegantly paired with simple black pumps while Alicia, sporting a more natural dark blonde hair colour, rocked a dazzling silver and grey dress with black edging.

The films male lead, Hugh Jackman, was unable to make the première as he is in London promoting his other movie, Real Steel.
