Hunter Biden has hit back at a sensational lawsuit claiming he fathered the child of an Arkansas woman while he was living with his late brother Beau's widow.

Former college basketball player Lunden Roberts filed a petition for paternity and support in May alleging Biden was the biological father of her one-year-old baby.

Roberts, 28, asked the court to 'establish paternity' while seeking child support, health insurance, and legal fees from the former vice president's son.

In a response filed on Monday and exclusively obtained by DailyMail.com Biden has denied all allegations and is demanding the suit be tossed.

In a response filed on Monday, Biden has demanded the suit be tossed while stating he is yet to be officially served with a court summons

The 49-year-old newlywed also states he is yet to be properly served with a summons.

In June, Roberts's attorney Clint Lancaster said he had been in touch with Biden's attorney in a bid to settle the issue privately but had been unsuccessful.

Roberts, who lived in Washington, D.C. for two years where she studied at George Washington University, has refused to comment on her relationship with Biden who is more than 20 years her senior.

A man at her family's isolated home in Southside, a town just outside Batesville, Arkansas, refused to speak, telling DailyMail.com: 'There's no story here.

'I don't mean to be rude but you have to leave.'

Lancaster did not return calls from DailyMail.com. He told The Arkansas Democrat Gazette that Roberts wants to be left alone but he confirmed she is seeking money from the former vice-president's son.

'She really values her privacy. This is a parenting and child support issue between her and Mr Biden,' said Lancaster.

'She really does not want this to be a media spectacle. She does not want this to affect Joe Biden's campaign.

Biden married 32-year-old Melissa Cohen in May this year, a month after splitting from Hallie

At the time of her pregnancy, Hunter was in a relationship with his late brother Beau's widow Hallie (shown together in August 2017, several months before he is alleged to have impregnated Lunden)

Biden (seen left with dad Joe) has since gone on to marry a woman he had only known for a few days after splitting with late brother's Beau's widow in April

'She just wants this baby to get financial support from the baby's father, Lancaster added.

'We have been in contact with Hunter Biden's attorney,' Lancaster said. 'We have attempted to work with Hunter and his attorney to settle this issue but that has not been successful.

'We are attempting to serve Mr. Biden,' he said.

In her lawsuit, filed on May 28, Roberts said she and her baby are living in Independence County, Arkansas, which includes both Batesville and Southside.

She said her child was born in August last year. She referred to the infant, now 10 months old, as 'Baby Doe' and did not say whether it is a boy or girl.

She asked the court to 'establish paternity of the child, finding that (Biden) is the child's biological father.'

She also asked the court to order Biden to pay child support and health insurance for the child.

Her friends and family held a baby shower for her shortly before she gave birth.

Roberts was a star basketball player at Southside High School and then went on to play for the University of Western Illinois before transferring to Arkansas State, where she played for the university's team, the Red Wolves.

According to the university, she was named to the Arkansas All-State team during her high school senior year and also played in the all state softball game. Her bio said 'she also enjoys hunting and shooting skeet.'

Lunden graduated from Arkansas State in 2014 with a Bachelor of Science degree in Interdisciplinary Studies, and later dropped out of a masters degree course at the George Washington University

In her lawsuit, filed on May 28, Roberts said her child was born in August last year and referred to the 12-month-old as 'Baby Doe', failing to specify whether the child is a boy or a girl

Her Western Illinois coach Leslie Crane said during her time there: 'Lunden is a great ball handler and can finish at the glass or with a jump shot. She is very savvy on the floor and has a lot of game experience.'

She graduated from Arkansas State in 2014 with a Bachelor of Science Degree in Interdisciplinary Studies. She then went on to study at the George Washington University in Washington D.C., where she did not complete her masters degree in crime scene investigation.

Hunter Biden has been surrounded by controversy over the past few years and it is feared his escapades could affect his father's chances of winning the Democratic nomination for presidency.

He was discharged from the US Naval Reserve in 2014, less than a year after being commissioned, after testing positive for cocaine and then his name, address and email were included when the cheating website Ashley Madison suffered a security breach in 2015.

Hunter, 49, has been surrounded by controversy over the past few years and it's feared his escapades could affect his father's chances of winning the Democratic nomination for presidency. He separated from his first wife Kathleen in October 2015. She claimed in court records afterwards that he spent their money on prostitutes and drugs

He left his first wife Kathleen — the mother of his three daughters — in 2016 after 22 years of marriage and moved in with Hallie Biden, the widow of his elder brother Beau, who died from brain cancer the previous year.

In the divorce, his wife claimed he had 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.'

Biden, an attorney with offices in Washington, D.C., split with Hallie earlier this year and on May 16 he married 32-year-old South African Melissa Cohen, whom he had only known for ten days. She had been living with a boyfriend up until April.

He would have been dating his sister-in-law when Roberts got pregnant in late 2017.

His business ties to various Ukrainian oligarchs have also garnered bad publicity for his father's presidential campaign.

Efforts to contact Biden were unsuccessful.
