Joe Biden's son Hunter has been a married man for nearly a month, secretly tying the knot with a South African activist, pictured exclusively by DailyMail.com.

Hunter Biden, 49, wed Melissa Cohen, 32, 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.

Cohen is an activist, traveling to Africa and Indonesia to support indigenous tribes.

The divorcée is originally from Johannesburg and now lives in Los Angeles. The newlyweds had a 'whirlwind romance' after meeting in early May.

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.

TMZ was the first to report the marriage.

A friend of Cohen's said the newlyweds met in May and had a whirlwind romance, even getting matching tattoos, they told E! News.

Cohen's father Lee, who still lives in Johannesburg with her mother Zoe, told the New York Post: 'She seems very happy. I’ve only spoken to Hunter briefly.

'She’s a very special girl. She has lots of poise and she’s very present.'

Representatives for Joe Biden have not yet responded to DailyMail.com's request for comment.

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.

Jill Biden wrote: 'When I’m around my grandchildren, I remember how incredible life can be...congrats Maisy! Beyond proud and filled with joy to see you graduate today.'

There was no sign of Cohen.

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, 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.

In 2016, Biden said he didn't run for president because he was grieving over Beau's death and was notably mum on his son Hunter's tawdry affair that tarnished his family's wholesome reputation.

After Beau's death in 2015, Hallie began to rub shoulders with Beau's lawyer younger brother Hunter in 2017.

Earlier this year, Hunter opened up to Vanity Fair saying his personal life would not affect his father's White House bid.

'Even though my life has been played out in the media, because I am a Biden, my father never once suggested that the family’s public profile should be my priority.

'The priority has always been clear for my dad, as it is, now, for me: Never run from a struggle. Love people and find a way to love yourself,' he said.

'My father has always been proud of me — whether when I was volunteering for the Jesuits, or working as a lawyer . . . And he remains proud of me today. He loves me.

'And he loves the American people far too much to let any form of adversity stand in the way of service,' Hunter said in a statement in January.

Hunter dated widowed Hallie Biden (pictured together) for two years following his brother's death from brain cancer. At the beginning of their relationship, Hunter was still married to his then-wife Kathleen, though they had been estranged. That divorce was finalized in April 2017

Hunter was married to Kathleen for 23 years, having three daughters, before they finalized their divorce in April 2017.

Their divorce was bitterly contested with Kathleen citing 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.'

She accused Hunter of purchasing a large diamond, estimated to be worth approximately $80,000.

At first, he denied being in possession of the gem but later admitted to having it, just days before it was revealed he was dating Hallie.

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.

'We are all lucky that Hunter and Hallie found each other as they were putting their lives together again after such sadness. They have mine and Jill’s full and complete support and we are happy for them,' they said.

Hunter and Hallie began dating after the death of her husband Beau Biden - former Vice President Joe Biden's elder son. Beau passed away from brain cancer in 2015 at age 46 (pictured together left in 2011). Then in 2017 she began to date Beau's brother Hunter who was still married to his then-wife Kathleen (pictured together right in 2016)

Around the same time Hunter finally confirmed their relationship saying: 'Hallie and I are incredibly lucky to have found the love and support we have for each other in such a difficult time, and that’s been obvious to the people who love us most.'

'We’ve been so lucky to have family and friends who have supported us every step of the way,' he added.

Hunter is a partner at Rosemont Seneca Partners LLC, which is run out of D.C.

He also served in the armed forces as a direct commission officer in the U.S. Naval Reserve in May 2013. He was ousted from the Navy reserve in February 2014 after he failed a drug test, testing positive for cocaine at the age of 44.

Hunter Biden's name also came up following the hack of the Ashley Madison extramarital affair website.

Conservative news site Breitbart reported in August 2015 that a Robert Biden (Hunter's given name) was found among hacked records, but Hunter denied it was his.
