Beyoncé has sparked fresh rumours that she is pregnant.

A picture posted on the singer's Instagram page sees her buried in the sand at the beach, with a mound on her stomach resembling a baby bump.

Beyoncé welcomed her and husband Jay Z's first daughter Blue Ivy Carter into the world in January 2011.

In 2013, she had to deny reports that she was pregnant for a second time after cancelling a show on her world tour.

It was recently announced that Beyoncé will feature on the upcoming Fifty Shades of Grey soundtrack.

Meanwhile, Beyoncé, Jay Z and Timbaland are reportedly being sued over their song 'Drunk in Love'.

Hungarian Roma singer Monika Miczura Juhász (professionally known as Mitsou) has accused the trio of illegally sampling her voice for a section of the song.
