THIS is the unbelievable moment a widow twerks against a cardboard cutout of her dead husband – just next to his open casket.

A reggaeton singer hired for the funeral provided the upbeat music the grieving woman danced to while funeral-goers cheered her on.

Dressed in black, the widow is captured rubbing her behind on the life-sized printout of her late partner in Peru.

Onlookers are heard whooping and cheering her on at the funeral.

And even the sad event’s entertainment – a singer known as El Cangri del Callao – was egging on the widow during his performance.

He even encourages fellow mourners to join in the raunchy dance at the wake.

The singer later shared the unbelievable clip on his Instagram page, where it went viral with 4.3 million views and thousands of comments.

One local said: “Hi bro, I’m going to die on 23 July.

“Are you available?”

Another added: “They are very young, but in my time we cried at funerals.”

“Widow finds five new loves… at the wake”, someone joked.

And: “We can see how that stupid music makes people stupid.”

One other comment pointed out how a “farewell should be joyful, not sad”.

While a fellow performer said: “I’ve performed funerals and wakes, but always from a very different tone to what this video shows.

“I’ve never had the opportunity to capture a farewell from such a luminous, vivid perspective.”

Meanwhile, a mere few days ago, the haunting moment a teen gave a tearful funeral eulogy to her slain mother and stepdad that later made her the prime suspect in their murder was captured.

Sarah Grace Patrick, 17, now faces two counts of murder and two counts of aggravated assault in connection to the shootings of Kristin Brock, 41, and James Brock, 45.

The chilling video of Patrick’s eulogy shows the teen in a pale blue dress, standing before mourners at the lectern of the Catalyst Church in Carollton, Georgia.

She said: “I just wanted to say goodbye to my mom and James since we never got the chance to.”

Patrick called her mother a “beautiful kind soul” and told mourners she’d always be her “sunshine”.

Now, the same speech that drew tears from the crowd is drawing scrutiny from law enforcement.
