The 31-year-old, who welcomed her first child - daughter Blue Ivy Carter, in January 2012, is said to be expecting again, reported New York Post. According to reports the pop superstar is said to have carefully hidden her baby bump in a high-waisted Givenchy gown at the MET Gala.
The 'Girls Run the World' hitmaker's spokesperson couldn't be reached for comment. Beyonce Knowles recently admitted she would love to give her 18-month-old daughter a sibling, because she enjoyed such a close relationship with her younger sister Solange Knowles, 26, when they were growing up.
"I would like more children. I think my daughter needs some company. I definitely love being a big sister."
