Megan Fox welcomed her third child, a son named Journey, only nine months ago.And the Transformers star lost the weight very quickly, wowing her fans within weeks of leaving the maternity ward.

On Friday the wife of Brian Austin Green gave a hint at how she was able to shed the weight when she was spotted leaving a yoga session in LA.

'I knew I was always going to be a mother; I felt like that was always a big part of my path,' she said in June on Chelsea Handler's Netflix series, Chelsea.

'But I never knew I was going to have three in such rapid succession.' Megan and Brian's son Journey River Green arrived in August.
