Beyonce has deflected a question about her rumored pregnancy.

The "Grown Woman" singer - who has a 14-month-old daughter Blue Ivy with her rapper husband Jay-Z - played coy regarding speculation she is expecting her second child, joking that she hadn't heard about the rumors. When quizzed about reports she is pregnant at the Sound of Change charity concert in London on Saturday, she said with a laugh, "What kind of rumors? What? Huh? I don't know what you're talking about."

After the interview for the Today Show - which aired this morning - host Savannah Guthrie said, "Mystery remains unsolved." Although Beyonce, 31, and Jay-Z, 43, have remained tight-lipped about her rumored pregnancy, the singer appeared to dispel speculation by posting a photo of her and her husband - real name Shawn Carter - enjoying a bottle of wine last week. In the snap, Beyonce can be seen sitting on Jay's lap as she takes a tall sip from her wine glass while the "Run This Town" rapper watches on.
