A pair of super slimmers from Hounslow met Peter Andre at a national awards ceremony.
Ms Maskell runs a Slimming World group at Inverness Lodge Social Club, Brentford every Monday and North Hanwell Baptist Church Hall, London every Wednesday.
She described meeting the Mysterious Girl and Insania singer at the ceremony in Birmingham last month as the prefect end to the year.
"I'm so proud of all of our members. They've lost fantastic amounts of weight throughout 2014, with many of them reaching their target weights and improving their health substantially," she added.
Ms Brennan, who runs classes at Hounslow Conservative Club, in Osterley, every Tuesday, helped members lose a total of 150 stone during her first year as a Slimming World consultant. Since September this year, members attending her groups have lost a combined 118 stone.
She said: "Everyone will be sure of a fab start with Slimming World this new year and even if people have struggled to stick to weight loss plans in the past, I know we can help them to make a change for life this time around – my members and their success are proof of that."
Mr Andre, who now presents the DIY show Peter Andre's 60 Minute Makeover on ITV, praised their work and that of other Slimming World consultants who are helping people achieve their goals.
He said: "Being in the public eye there’s a lot of scrutiny and if you put on even a pound or two the magazines and newspapers are extremely quick to point it out, so I’ve always tried to take care of myself and watch my weight.
"However since becoming a dad I’ve realised it’s about more than just looking good; it’s much more important to me that I’m fit and healthy and setting a good example to my children.
"At the awards I met lots of people who’ve lost incredible amounts of weight and it has completely transformed their lives – and their families' lives too. They're eating more healthily and being more active, and so are their families.
"And every single one of them told me that they couldn’t have made those changes without the support of their Slimming World group and their consultant, so people like Lisa and Toni are clearly very important."
