Rapper 50 Cent has posted on his Twitter bad taste mock-up photos of what Beyoncé and Jay-Z's new baby 'could' look like.

50 Cent took to the social networking website only days after the couple gave birth to their new daughter Blue Ivy Carter to spread images of Jay-Z's head superimposed onto the body of a baby.

Before giving the link, he tweeted:

"Yal play to much congratulations to JAYZ and Beyonce BABY #BlueIvyCarter IS GEORGOUS."

50 Cent has a bit of previous history with Jay-Z - once claiming that he was "only famous for marrying Beyoncé" - and has mentioned in the past that the pair aren't really friends.
