Jay-Z, is rumoured to be expecting the couple's first baby after nearly two years of marriage.
According to US website Destiny's Child star, who recently collaborated with Lady GaGa on the number 1 hit Telephone, is thought to be working through her pregnancy up until her due date.
Beyonce wed the Empire State Of Mind rapper in a candlelit ceremony back in April 2008 but the couple have always tried to keep their relationship out of the public eye.
However Knowles, 28 has always spoken publically about her desire to have a family.
She has previously stated: "Well, I'm an ambitious woman, and when I do anything, I do it really hard,"
"If I work out, I work out really hard, and if I love somebody, I love them all the way.
She added: "I'm very loyal. I want a whole bunch of kids - but after I've got certain things out of my system first."
A spokesperson for the couple has refused to commen at this time whilst Beyonce's publicist Alan Nierob told OK: "We don't respond to private matter issues."
