Rebecca Loos back in a bikini after giving birth

She gave birth to her first child just eight weeks ago – but Rebecca Loos is already back in a bikini. And at 9st she says she is 5lb lighter than before she became pregnant. The new mother, infamous for her alleged four-month affair with David Beckham, has lost 2st 7lb since giving birth to son Magnus in July – DailyMail reports. Rebecca Loos gave birth 8 weeks before the above photo was taken.

She tells Now magazine: ‘Obviously I was very busy with the baby and I wasn’t sleeping much and felt exhausted, so it was important that I lost the weight slowly and sensibly.

‘I didn’t want to starve myself and had to be careful about what I ate because I was breast feeding.

She also embraced exercise – walking every day with her son in his buggy, running once a week and doing 20 pelvic bum lifts, squats and lunges three times a week plus 40 sit-ups every other day.

She says: ‘The weight started to fall off immediately. After two months I’d lost a whopping 2st 7lb and felt full of energy.’

Six weeks after giving birth he 32-year-old claims she was already back in her size 10 jeans.

Rebecca, who is 5ft 7in, normally weighs around 9st 5lb but reached a peak of 11st 7lb during pregnancy.
