Beyonce Goes All Britney, Lets a Nipple Slip

It's difficult to keep giant boobs down.

Just ask a certain pop singer. Oh, you thought we were talking about the numerous Britney Spears nipple slips? Not this time.

Beyonce Knowles did her best impression of Jayden James' mother over the weekend, as a concert performance got slightly out of hand. Or out of shirt, to be exact.

You have to look closely - come on, don't be shy - to get a view of some Beyonce nipple action, but the private parts are definitely made public in the photos below. Sorry, Jay Z. But you've got nothing to be ashamed about here.

We wonder if Jennifer Hudson will just tear off her shirt next. In this highly publicized feud between the pair of divas, you've gotta stay one step ahead of the competition. 

Meanwhile, as you stare at Beyonce's boobs, let us know what you think about this singer's hair. Is it better curly or straight? And whose nipples will we see next?

The good money is on a Britney Spears or Lindsay Lohan reprisal, if you ask us.
