US singer and actress Beyonce said speculation she and husband rapper Jay-Z paid a surrogate to carry their daughter is \"just crazy.\" \"That was crazy. It wasn\'t hurtful, it was just crazy,\" People magazine\'s 2012 Most Beautiful Woman told the publication. \"[I thought] \'Where did they come up with this?\'\" Beyonce\'s mother, Tina Knowles, appeared more upset by the speculation, calling the rumors \"cruel.\" \"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,\" Knowles said. \"As a mother it was painful for me to hear the crazy rumors. And I even had people ask me, which was so ridiculous.\" Knowles quashed suggestions her daughter was wearing a prosthetic baby bump during an Australian television interview when some fans said the bump folded, People reported Sunday. \"It was a fabric that folded -- does fabric not fold? Oh my gosh, so stupid,\" Knowles said.
