Ashlee Simpson has probably become more conscious of her weight after her sister Jessica Simpson was signed as the face of Weight Watchers.

Jessica Simpson put on four stone during her pregnancy, after admitting she indulged her cravings of macaroni cheese and pop tarts a bit too much.

And it seems that the pair are closer than ever after Jessica Simpson announced her second pregnancy on Christmas Day.

Ashlee revealed that Jessica is 'a strong woman' who she can 'look up to'.
