Beyonce Knowles has criticised claims that she used a surrogate for her first daughter with husband Jay Z, stating that the rumours as "crazy".

During her pregnancy it was reported that the Crazy in Love singer’s stomach appeared to fold inwards during a TV interview.

Following the incident rumours rapidly started suggesting that Beyonce was wearing a prosthetic baby bump to fake her pregnancy.

In a recent interview with People magazine Beyonce said: "That was crazy. It wasn't hurtful, it was just crazy. Where did they come up with this?"

Beyonce's mother Tina was also left outraged over the rumours adding: "I thought it was very unfair and very cruel that someone would think that someone would be that diabolical to keep up a charade like that for nine months.

As a mother it was painful for me to hear the crazy rumours. And I even had people ask me, which was so ridiculous."
