She's been keeping fit with regular Bikram yoga sessions, which sees people exercise in 40C heat to improve their flexibility. But it seems Imogen Thomas may have forgotten to pack a top to wear after the session, as she was seen leaving the yoga class this morning wearing just a crop top and low-slung trousers
- despite temperatures in London dropping below 0C. However, the 29-year-old model looked entirely unfazed by the cold weather and snow on the ground as she made her way to her car, where she then covered up in a striped jumper.

Imogen has been working hard to regain her pre-Christmas regime, and said in an interview with Closer magazine this week that it is binge dieting which has caused her weight gain. She said: 'People think I’m confident with my body, but I’m not. I’m pushing a size 12, which I know isn’t fat, but it’s more about how I feel about it.
