Beyonce and Jay-Z leaving club after 5am

Beyonce Knowles-Carter sparked pregnancy rumors when she departed The Arts Club with a jacket placed strategically over her swollen abdomen. Beyonce, 33, and her aging rapper husband Jay Z, 45, dined at the private club with friends Will.I.Am and Swizz Beatz in Mayfair, London on Thursday. The couple already have one daughter, Blue Ivy, 2, though her maternity is in doubt. Beyonce looked stunning in a short, striped white dress and a pair of black shoes.
