Beyonce and Jay Z expecting twins

Pop superstar Beyoncé announced Wednesday that she is pregnant - this time with twins.

Beyoncé -- who already has a five-year-old daughter with her husband, rap mogul Jay Z -- showed a picture of herself on Instagram in lingerie, her arms cradling her rounded belly.

“We would like to share our love and happiness. We have been blessed two times over,” Beyonce wrote.

“We are incredibly grateful that our family will be growing by two, and we thank you for all your well wishes,” she wrote, signing with Jay Z.
