Playing with her toyboy! Allison Janney, 56, shows off her 'pretty handsome' lover Philip Joncas, 35, at Sundance Film Festival

The key to being a successful cougar is to have sharp claws.

And Mom star Allison Janney certainly seems to have dug them in deep to her toyboy lover Philip Joncas after the pair were pictured in apparent bliss as they attended the Sundance Film Festival at the weekend.

Th 56-year-old and her much younger man seemed entranced with each other as they relished the atmosphere at the star studded event in Park City, Utah.

After walking the red carpet together at the premiere of her film Tallulah, the pair gazed lovingly into each others eyes as they perused some watches at a gifting suite in Kari Feinstein's Style Lounge.

Speaking at the first event, she told E,'he's pretty handsome,' but added that despite the fact they have been dating for a year, they will not be getting married any time soon.

West Wing favourite Allison said: 'I don't believe in that institution.'

It was certainly easy to see why the production coordinator and artist is so smitten with his older woman as she did the rounds at the popular festival.

For she looked in sparkling form indeed in a tight green polo neck and matching racy leather trousers.

And she took the opportunity between events to swap from her premiere leather boots for more comfortable Ugg-styles footwear when they went to Kari Feinstein's Style Lounge.

The hard-working actress, who has won seven Emmys,  was not content to rest on her laurels after Saturday's events however.

For on Sunday she was taking part in a discussion about Tallulah with the film's star Ellen Page at the The IMDb Studio.

The film tells the story of a young free-spirited woman who rescues a baby from an irresponsible mother and pretends the child is her own with the help of her ex-boyfriend's mother.
