Rapper 50 Cent took to Twitter to post mock photos of Jay-Z and Beyonce's newborn baby, possibly reigniting a feud between the two hip hop stars.

The rapper posted the Photoshopped images earlier this week, which feature a baby with Jay-Z's face superimposed on it with the message, "Yal play to much congratulations to JAYZ and Beyonce BABY #BlueIvyCarter IS GEORGOUS."

There has been bad blood between the two rappers since 50 Cent said that Jay-Z only became famous when he married pop superstar Beyonce in 2008. Although by the time the two wed in 2008, Jay-Z had already released 10 albums, several of which reached number one on the Billboard charts.

While in Las Vegas for the Consumer Electronics Show to promote his brand of headphones 50 Cent also posted a number of images of himself with boxer Floyd Mayweather posing with stacks of cash in his hotel room, tweeting "I was thinking I could make a lot of money one day," and "We made it mom top of the world!!!!.( James cagney voice)lol"

The rapper posted follow-up tweets, seemingly indicating that he did not create the images: "I would never make a picture like that its all over my time line yal play to much I'm sure Jay is the happiest he's ever been in his life." He then posted about his own child's birth: "I remember when MARQUISE was born I was so happy. I want to have another kid one day."

50 Cent, whose real name is Curtis Jackson III, also posted some advice to the new parents: "they will pay a million dollars for a picture of that baby - trust me."

Rumors have been circulating since Beyonce gave birth to Blue Ivy on Saturday night that the couple are shopping the first images of the newborn around to magazines for a multi-million dollar payday.

The couple reportedly left New York's Lenox Hill hospital with baby Blue Ivy in the early hours of Wednesday morning.
