Pop superstar Beyonce has fuelled speculation that she is expecting her second child after she was spotted rubbing her stomach during her birthday celebrations in Italy.

According to celebrity gossip site, MediaTakeOut.com, the Drunk in Love singer displayed a hint of a growing bump on board a yacht in Corsica and even went out of her way to show it off.

"Beyonce was spotted consistently rubbing her belly – and she had a specially made dress – with the belly cut out. And it that's not enough – Bey had gold paint on her tummy, to make the announcement loud and clear!", the website reported.

Queen B, who recently took home the coveted Michael Jackson Vanguard award at the 2014 MTV VMAs, is currently enjoying some down-time with Jay Z and her family in Europe.

As well as being photographed cradling her stomach, Beyonce was wearing loose-fitting clothing.

OK! magazine previously reported that the Jay Z has become fiercely protective of his wife in recent weeks.

"For the last month, Jay has been fiercely protective of her, just like he was when she was expecting Blue Ivy. He's been doing everything he can to ensure that Bey is in a stress-free bubble", a source told the magazine.

"He's informed their entire entourage that they need to use relaxed voices, mellow lighting and listen to only soft music, and he's said that all of the food Beyonce eats should be organic."

"He's really doing his best to make sure that she's as comfortable and healthy as possible", the source continued.

Although the power couple have yet to confirm or deny the rumours, there is guaranteed to be plenty of speculation that it's a desperate move to save their marriage.

Ever since footage emerged of Beyonce's sister Solange Knowles attacking her brother-in law in a lift after the MET Gala, the power couple have been dogged by divorce rumours and Jay Z has been linked to multiple women.
