This is the hilarious moment a cheeky monkey pulls down a woman’s dress as she poses for pictures with the primate.

Sarah Wijohn, 21, from New Zealand, was on a family holiday to Bali, Indonesia, to celebrate her 21st birthday when the group of relatives visited a forest on May 29.

The young woman sat on a wooden bench when one of the wild creatures climbed onto her lap. She smiled and tilted her head while her family took pictures.

But when they were almost finished and the monkey appeared to be stepping down, it suddenly turned back around and yanked down the top of Sarah’s black dress.

The woman’s strapless nude-coloured bra and part of her breasts were exposed to passers-by.

Onlookers burst out in laughter at the amusing incident and Sarah saw the funny side, laughing out loud and clutching her cleavage as the cheeky monkey scurried away.

Sarah’s mum Katrina said: ''We had a good laugh because of the monkey. Overall, our Bali stay has been amazing.''

The unexpected incident was captured at the Sacred Monkey Forest Sanctuary, which is the natural habitat of Balinese long-tailed Monkey.

The young woman sat on a wooden bench when one of the wild creatures climbed onto her lap. She smiled and titled her head while her family took pictures.

But when they were almost finished and the monkey appeared to be stepping down, it suddenly turned back around and yanked down the top of Sarah’s little black dress.

The attractive woman’s strapless nude-coloured bra - along with far more of her breasts than should have been on show - were exposed to passers-by.

Onlookers burst out in laughter at the amusing incident and Sarah saw the funny side, laughing out loud and clutching her cleavage as the cheeky monkey scurried away.
