In her recent new Mango fashion campaigns Scarlett Johansson showed off an enviably fuller figure. Yet papped, and unairbrushed, images of her hanging out and jogging with new man Sean Penn have revealed a less flattering body image with the actress boasting a prominent bump.

Now sources believe the 26-year-old actress is pregnant with her 50-year-old BF’s baby. While ScarJo denies being preggars, one source claimed, “Scarlett’s keen to be a young mum and does not plan to be the sort of women who leaves motherhood too late and starts worrying about her biological clock ticking.”
