Hunter Biden's new wife is said to have been living with her real estate developer boyfriend of two years just weeks before secretly marrying the former vice president's son, who she'd reportedly only known for 10 days.

Melissa Cohen, 32, was living with Rob Mendez up until April of this year and the former couple were continuing to 'hang out' into May - when she met 49-year-old Hunter - according to Page Six.

The South African activist, who started dating Mendez in July 2017, married Hunter in Los Angeles on May 16 - just weeks after reports surfaced he had called it quits with his late brother Beau's widow Hallie Biden in April after two years of dating.

Pals of the divorcée, originally from Johannesburg, are said to have been stunned the wedding with one commenting: 'She just broke up with Rob.' Another added: 'So I'm quite shocked by this being so sudden after their breakup.'

Mendez said he had 'a very, very good relationship' with Cohen, calling her 'an amazing girl'

The dad-of-three said he credits Cohen with 'turning our house around', bringing a 'properness' to the home he shares with his children aged 10, 11 and 13. A friend of Cohen's said she lives in Los Angeles and the newlyweds met in May, having a whirlwind romance, even getting matching tattoos as a sign of their love

Mendez told Page Six they had 'a very, very good relationship' , adding: 'The best I've ever had. She found love and she's happy. She's honest to God an amazing girl; extremely intelligent.'

They split because 'marriage and kids were in her future, but for me they just aren't' but he says he has 'nothing but love' for Cohen, who was also previously married in 2011.

Cohen's brother told DailyMail.com in a statement on behalf of her family: 'We are very happy for them and welcome Hunter to the family.'

The hasty vows in California, plus Hunter's recent breakup hint that presidential hopeful Joe Biden and the rest of the Biden family were not in attendance for the wedding.

On Sunday, Jill Biden posted a family photo celebrating Hunter's daughter Maisy's graduation from high school in Washington D.C., but absent from the group shot was Hunter's new wife.

On Sunday, Joe, Jill, their daughter Ashley Biden, Hunter and Hunter's three daughters, Maisy, Naomi and Finnegan, whom he shares with his ex wife Kathleen, were all pictured in a celebratory graduation photo posted on Instagram.

There was no sign of Cohen, with whom Hunter is also said to share a matching tattoo.

Hunter recently broke off his relationship with widowed Hallie after dating for two years - beginning in 2017 - following Beau's death from brain cancer in 2015.

At the beginning of their relationship, Hunter was still married to his ex-wife Kathleen of 23 years, though they had been estranged. That divorce was finalized in April 2017.

In late April, it was reported Hunter split from Hallie, coming on the heels of Joe's presidential campaign announcement.

Sources say the breakup was 'amicable' but the reason behind the split remains unknown.

His divorce from Kathleen was bitterly contested after she cited irreconcilable differences due to how he spent 'extravagantly on his own interests (including drugs, alcohol, prostitutes, strip clubs and gifts for women with whom he has sexual relations), while leaving the family with no funds to pay legitimate bills.'

The Biden family stayed quiet when news broke of Hunter and Hallie's relationship.

In 2017, Joe and Jill broke their silence and announced their support of the duo.
