It would seem ex-Bachelor star Zilda Williams (pictured) has returned to her raunchy glamour model days

She was flaunting her DD-cup size curves on the pages of lads' mags long before finding fame on The Bachelor last year.

And it seems Zilda Williams has made a return to her raunchy glamour model days, as she was spotted posing TOPLESS at Sydney's Hermit Bay this week.

The 33-year-old socialite flashed her surgically enhanced chest for a risqué beach photo shoot on Friday - stripping down to just a skimpy pair of bikini bottoms.

The New Zealand-born reality star was seen arriving at the quiet destination in Vaucluse wearing her favourite strappy black bikini.

She then posed for several snaps with a male photographer - who, it is believed, is shooting Zilda for a European magazine centerfold.

But it wasn't long before the ex-Zoo Weekly cover girl decided to take things a step further - by going completely topless.

She whipped off her bikini top and proudly flaunted her ample chest - barely concealing her modesty with a 'hand bra' pose.

Zilda, who currently resides in Sydney, also put on a very X-rated display as she perched on her knees and showed off her derrière to the camera.

Meanwhile, in-between shots, the blonde beauty could be seen readjusting her Brazilian-style bikini bottoms.

In contrast to her typically straight locks, she opted for a messy beach hair look which fit the outdoor setting.

Zilda, who was the first to be eliminated by Melbourne entrepreneur Sam Wood on The Bachelor last year, recently celebrated her 33rd birthday in Double Bay.

Meanwhile, the upcoming series of the Network Ten dating show is currently being filmed 45 kilometres away in the semi-rural suburb of Dural.
