Beyonce Gives Birth to Twins

Beyonce and Jay Z have welcomed their twins into the world ... TMZ has confirmed.

There have been rumblings all week Beyonce gave birth in a Los Angeles hospital. There were signs she might have given birth to a boy and a girl based on balloons that were delivered to a hospital, but no hard evidence so far.

President Obama intimated a few days ago the twins might be girls, but again ... nothing concrete.

The evidence seems to be mounting ... 5-year-old Blue Ivy could earn some serious babysitting cash.
