Blue Ivy is about to become a big sister...twice.
Beyonce and her husband, Jay Z, announced Wednesday on Instagram that the superstar singer is pregnant with twins.
``We are incredibly grateful that our family will be growing by two,'' said a statement signed ``The Carters.'' The news accompanied a photo of Beyonce showing a baby bump while wearing just a bra, underwear and a veil.
Their daughter, Blue Ivy, was born in 2012.
