At a taping for Thursday's Ellen, the clothing designer appeared to clear up recent reports that the Grammy winning singer was expecting her first child.
"The truth is that's it's not Beyoncé that's pregnant. It's me," Knowles told host Ellen DeGeneres.
Knowles then revealed that she was joking, but she also made it clear that Beyoncé, 29, isn't having a baby either.
"No, no it's not true. Not right now," she said.
Beyoncé and rapper Jay-Z married in April 2008.
