Katy Perry pops out on holiday

POP superstar Katy Perry almost spilled out of her candy-striped bikini as she enjoyed a beach day with her busty pal.

The I Kissed A Girl hitmaker looked sensational in her stripy two-piece.

But it was her topless friend who stole the show.

Katy, 32, chose to squeeze her ample assets into a bikini but her fellow beach babe chose to let her pert pair hang loose and free.

Both girls let their assets take centre stage as they took a break on Italy’s Amalfi coast and stripped off for their sun-soaked getaway.
