The 29 year old is expecting her first child with fiance Jason Statham, 50, and posted a bikini clad picture, baring her burgeoning baby bump.
Rumours were in the air when Rosie hit into the new year with a picture of herself clad in a loose maternity inspired dress, and finally has confirmed her baby's impending arrival.
With a hand on her back, showing off her bump in a Missoni bikini, Rosie beams and eludes the pregnancy glow, and seems the happiest in the snap taken by her fiance, with whom she has been together since 2010.
The 'Mad Max' actress had always talked about seeing herself as a mum, and we are sure she would be a lovely one indeed.
Though there is no word on when the baby is due, Rosie seems to be about five to six months pregnant in the picture with a picturesque tropical paradise backdrop.
