The couple are currently on the European leg of their joint tour and on Friday night (12 September) Jay-Z is said to have changed the lyrics to one of his songs to suggest his superstar wife is expecting again.
The rapper, 44, reportedly sang the words "cause she pregnant with another one" during the first of two Paris shows, says Radar.
According to French gig goers, Jay-Z changed the words in his song 'Beach Is Better' sparking massive speculation about what's in his wife's belly!
Beyoncé, 33, and hubbie Jay-Z welcomed their first child, daughter Blue Ivy, in January 2012.
Since then, she has made no secret of the fact that she'd like a brother or sister for her first born.
She told chat show host Oprah Winfrey earlier this year: "I definitely want another child. After this next tour, maybe I'll have another baby."
If the rumours are true, the fabulous news will silence critics who have been reporting that the pair are heading for divorce.
The parents, believed to be one of the richest power couples in the world, tied the knot in April 2008.
