Beyoncé has put an end to endless pregnancy rumours with a tactfully chosen Tumblr snap.

The 'Love On Top' singer shared a photograph of her on the social networking site last week, showing her sitting on her husband Jay-Z's lap, sipping on a glass of red wine as he gazes lovingly at her.

The cute picture was taken when the pair were in Berlin for Beyoncé's May 24 'The Mrs. Carter Show' tour date.

The R&B superstar - who has 14-month-old daughter Blue Ivy with Jay-Z - has been the subject of speculation since May when ''multiple sources'' claimed the star was pregnant after the Met Ball.

While the power couple have recently expressed their desire to have a second child in the near future, Beyoncé was quick to deflect the rumours when pressed about the subject.

Quizzed about the reports during the Sound of Change charity concert in London on Saturday (01.05.13), she laughed: 'What kind of rumours? What? Huh? I don't know what you're talking about.'

After the interview for the 'Today Show', host Savannah Guthrie concluded: ''Mystery remains unsolved.''
