Made In Chelsea's Spencer Matthews and Jamie Laing paid Â£4k to appear for charity As heirs to multi-million-pound fortunes, Spencer Matthews and Jamie Laing have little need to earn extra money on the side. But the Made In Chelsea stars had no qualms about pocketing Â£4,000 for appearing at a black-tie charity gala, despite turning up with eyes â€˜like saucersâ€™, dressed in jeans and leaving after less than an hour to go clubbing. The behaviour of the pair, both 26, was branded â€˜disgustingâ€™ by the eventâ€™s organiser, who says they were â€˜so smashed it was embarrassingâ€™ and has called on them to return their fees.Â In attendance:Â Spencer Matthews (left) and Jamie Laing with charity founder Niki Cunningham at the Harry Cunningham Trust fundraiser on Saturday evening Chelsea boys: Spencer Matthews (left) and Jamie Laing (right) attended the Harry Cunningham Trust fundraiser on Saturday night in Devon, but didn't spend much time there according to the event's host Matthews and Laing â€" in line to inherit Eden Rock Hotel St Barths and the McVitieâ€™s biscuits empire respectively â€" earned the money for appearing at a dinner for the Harry Cunningham Trust in Devon on Saturday. The trust was set up by Niki Cunningham, 31, in memory of her son Harry who died in 2012 when he was just a day old.Â Mrs Cunningham booked the reality television duo through agency Friday Flava to raise the eventâ€™s profile. She was promised they would stay for the dinner, as some guests had paid Â£115 to be seated at a table with a celebrity, pose for press pictures, attend a meet-and-greet and mingle with the crowd.Â She also paid for their dinners and hotel rooms, coming to a total of Â£360. Mrs Cunningham said she felt â€˜let downâ€™ after the pair said they had to leave because of filming commitments, despite being booked five months in advance.Â They stayed for less than an hour in total and walked out halfway through Mrs Cunninghamâ€™s presentation.Â Gala evening: Spencer and Jamie posed again with Niki and her husband Jamie at the charity event But Matthews and Laing were then spotted partying at the nearby Cosy Club bar and posted a selfie of themselves online from the first-class cabin of a train on the journey back to London.Â Hours later, Laing was photographed falling out of a club with blood on his face. Mrs Cunningham said: â€˜I was so angry with the boys. They were so selfish and arrogant. They had no idea what they were there for.Â They didnâ€™t introduce themselves when they arrived and there were no questions about the charity. I was taken aback. They were so rude. â€˜The security guards immediately told me something was up. The first thing they did when they arrived was head to the toilets. Draw your own conclusions.Â Drama: Jamie Laing looked worse for wear as he stumbled out of a London club in the early hours of Sunday morning Trouble: The Made In Chelsea star shocked onlookers due to having a bloodied mouth Help: The 26-year-old was rushed to a waiting car by a bouncer at 5.30am â€˜They posed for a few photos and tried to talk to a few of the guests but they were so smashed, it was embarrassing to watch.Â Then before we even sat down to dinner they said they were heading off. Given how well-off they are, youâ€™d expect them to be well brought up, charming and polite.Â It couldnâ€™t be further from the truth.â€™ Guest Lee Cameron, 40, added: â€˜They were late arriving. I would say they were there for an hour, tops. It was absolutely disgusting.â€™ Eton-educated Matthews says he will return his fee to the charity, but Laing â€" who went to school at the Â£11,075-a-term Radley College â€" has yet to make any such pledge.Â Mrs Cunningham had nothing but praise for other celebrities at the dinner, including Coronation Street actress Kym Marsh and X Factor singer Luke Friend. Last night a lawyer for Matthews said: â€˜As agreed beforehand, Spencer left the event early because he had filming commitments the following day, which he fulfilled. Prior to arriving, he was unaware that the evening was a charity event. He has happily donated his appearance fee to the charity.Â He apologises for any misunderstanding and wishes the trust the very best.â€™ Laing did not respond to repeated requests for comment.Â Date night: Corrie star Kym Marsh attended the fundraiser with boyfriend Dan Hooper Star performer: Niki and former X Factor star Luke Friend, who performed on the night Emotional: At one point up on stage, Kym was overcome with emotion with the charity's founder Niki Entertainment: Luke sang for the assembled guests at the Harry Cunningham Trust fundraiser
