A MALAYSIAN ex-king who split from his Russian model wife just weeks after their son was born has now claimed he might not be the baby's father.

Sultan Muhammad V of Kelatan gave up his throne in January months after marrying former Miss Moscow Oksana Voevodina, but the two divorced earlier this month.

The 50-year-old monarch has now cast doubt on the paternity of the couple's newborn.

Singaporean lawyer Koh Tien Hua, speaking on behalf of the sultan, told the Straits Times: “There is no objective evidence as yet as to the biological father of the child.”

He added: "On behalf of His Royal Highness, we request his privacy be respected."

Voevodina, 27, a former Russian beauty queen, is believed to have returned to Russia with the child, and last week claimed that she was still married.

Speaking to a Malaysian news outlet, she said: "This is an act of provocation. We have never been divorced."

In a video posted on Instagram, she also said: "I want to be the last person in his life, and I want to live with him until the end of my life."

But a copy of the divorce certificate has surfaced online and been confirmed to be genuine by a source of the New Straits Times.

The certificate, which bore the Kelantan state crest, said the divorce was registered on July 1, and is marked as being the wife's copy.

It indicated the divorce was registered in Singapore and was done by the utterance three times of the word "talak" - the most serious form of divorce in Islam.

The British-educated Sultan abdicated in January after the publication of revealing pictures and lurid sex claims about his new wife's past life as a reality TV show star in her homeland.

In the weeks after the birth of the couple's son on May 21, Voevodina posted a series of family photos to Instagram with messages in both English and Russian.

One photo shows the new mum cradling her baby's feet in one hand.

She captioned the snap: "21 May 2019 - the day when my life was divided into 'before' and 'after'.

"Everything that I was told about the changes occurring with a woman after the birth of a baby is true.

"This love is special. These feelings are completely new. I am grateful to Allah and my husband for our son. Now there are three of us."

The new mother also revealed her baby's full name as Tengku Ismail Leon Petra Bin Tengku Muhammad V Faris Petra.

Alongside the announcement were a series of glamorous new pictures from Voevodina's pregnancy and Moscow wedding.

In one snap, she wears a silk and lace dressing gown whilst cradling her bump.

The caption reads: "It was the most important and, at the same time, the most difficult period in my life.

"The last three months of pregnancy I spent in hospitals, staying in bed with (drips in) both hands. I had too many difficulties with pregnancy.

"The support of my closest people and my love for my son and Faith in the best helped me in that not simple time."

In another glamorous pregnancy snap, she refers to her new son: "One day you will see this photo. You are not born here yet.

"But I already love you with unconditional universal love …"

And recalling her Moscow marriage, she said: "I want to say thank you to the people who shared this happy moment with us and were together with us that evening!

"It was wonderful and beautiful wedding…"

Voevodina also confirmed she and the then king underwent a secret Muslim wedding some five months before her very public ceremony in Moscow, where she wore a dress she had been "dreaming about since childhood".

She and the former monarch will mark the anniversary of their nuptials this Friday.

WHO IS OKSANA VOEVODINA?

Voevodina is the the daughter of a Russian orthopaedic surgeon and won the Miss Moscow contest three years ago.

In November 2018, it was reported that the beauty queen took part in a reality TV show under a fake name where she romped in a swimming pool.

The show featured 11 young Russians thrust together at a luxury Sol de Occidente villa in Mexico belonging to Russian actress Zhanna Friske.

An advert for the programme said they "lived there making love to each other from time to time and emotionally discussing their relations”.

Reports surfaced she had had sex with male contestant Elisey Polischuk in a swimming pool.

Pictures from the show were widely publicised amid claims those in conservative Malaysia disapproved.

Voevodina, who converted to Islam to marry, adopted the name Rihana and is now known as Rihana Oksana Petra.

Some have suggested she has used the birth of her son to clear rumours that surfaced in January that her relationship with the ex-king was in trouble after his abdication.
