Scott Disick celebrates with Petra Ecclestone and husband after DNA test proves he's Mason's father... but Kourtney is a no-show

He’s had a tough few weeks after battling a paternity claim from a male model over his son Mason, but Scott Disick was in a celebratory mood on Thursday night as he was proved to be the father of his little boy.

Instead of heading out with his partner, and Mason’s mother, Kourtney Kardashian though, Lord Disick was spotted enjoying a dinner with Petra Ecclestone.
The 24-year-old Formula 1 heiress was joined by her husband James Stunt, 28, for the cosy dinner for three.

Scott, Petra and James enjoyed a dinner at Hollywood hotspot Madeo on Thursday night.

Kourtney’s man, 30, was looking dapper in a bright orange blazer which he paired with some off white trousers and a crisp shirt.

Completing his signature quirky style with a pocket square and some shiny black shoes, Scott was sporting a fair amount of of facial hair as he was seen departing the restaurant.

Scott’s dinner companion Petra also dressed up for the dinner.

The heiress, who gave birth to her first child Lavinia in February, showed off her tanned legs in a leather mini skirt.
The short number featured studded detailing, with the high hemline displaying a lot of leg.

Petra teamed her skirt with a simple black long sleeved shirt, which she tucked in to emphasise her waist.
Black heels and a chunky watch completed her look, whilst the blonde left her hair loose and added a touch of glamour with false eyelashes.

Whilst Petra and Scott had made the effort for their posh night out, the heiress’ husband James obviously didn’t get the memo.
The entrepreneur, who married Petra in 2011, wore a pair of jeans, a baseball cap and a black T-shirt and jacket as he escorted his stunning wife inside.
No doubt the trio were raising a glass to Scott’s good news, after his partner Kourtney put an end to paternity rumours involving her son Mason earlier in the day.
On Thursday, Kourtney announced that a DNA test had proven once and for all that Scott is the father to the three-year-old.

Kourtney was asked by model Michael Girgenti to allow Mason to undergo the test, after he claimed they slept together while she and Scott were on a break in their relationship in March 2009.
But lab results from tests taken on August 12 have proved his allegations are false.

Kourtney, who has always denied Michael's allegations, told E! News: 'After three-and-a-half years of lies being spread by an individual I met briefly at a photo shoot, I am setting the record straight that Scott is Mason's father.

'While it saddens me to have to address these ridiculous lies - especially when the truth was never in doubt - this story must be put to rest.'

However, Mr Girgenti appeared to not have accepted the results of the text as conclusive and plans to press ahead with the paternity lawsuit he filed earlier this month in which he claims he had 'unprotected vaginal sex' with Kourtney in March 2009 at his Glendale, California apartment.

'We don’t trust the results and believe it could have been fixed,' his spokesperson told Radar. 'Still going to court to fight for court ordered results.'
