Miss Bum Bum proves she isn't just packing booty with peek-a-boob selfie

SUZY Cortez's peach has been crowned the best in Brazil.

HOW LOW CAN YOU GO?: You can't call it a neckline when it's around your waist

But if her latest Instagram is anything to go by, the sizzling brunette's rump isn't the only asset she's proud of.

Donning a top so plunging it almost skims bellybutton, the brunette placed a game of "how low can you go" with her 316,000 Instagram followers and definitely won.

CRITICALLY ACCLAIMED: The ass-et that launched Suzy's career

Pouting up a storm with a Barbie-pink lip, the curve queen wears her tresses poker straight in the cheekily-angled pic, which sees her put her breast foot forward.

Alas, the grey ensemble attempting to contain her cleavage is fighting a losing battle.

Still, all's fair in love, war and selfies.

In another recent post, the vixen zooms in on her bare bubble but, which is sporting the tiniest tan line we've ever seen.

We guess it's testimony to her taste in minuscule swimwear, which seems to be her go-to uniform.

Not that she's getting many complaints.

The bombshell is currently in China promoting the Miss Bum Bum World Show.

In one clip of the Day Day Up show, two dancers strip off her skirt while she shakes what her mama gave her.

Hardly family viewing...
