Singer flashes grandma pants on stage

She’s known for her Bootylicious bottom, but Beyoncé Knowles is reported to have flashed a pair of unflattering knickers on her world tour.

The singer, 26, is said to have been wearing Bridget Jones-style granny bloomers under her shimmering silver mini-dress.

As she went to shake her booty on the Shanghai leg of her tour, Beyoncé revealed the sensible pants, reports the Daily Mirror.

And she teamed the look with ugly flesh-coloured hold ups.

Someone call the fashion police.
