The businessman, 40, is dating Fox News host Kimberly Guilfoyle, a source confirms to Us Weekly. Vanessa Trump filed for divorce in Manhattan Supreme Court in March. Trump Jr.is in the process of divorcing his wife Vanessa after 12 years of marriage.
Guilfoyle, a registered Republican, once let it be known that she was in talks with the Trump administration about possibly taking a job as the White House's press secretary.
"We will always have tremendous respect for each other and our families", the former couple said in a statement.
They separated in 2005 when she moved to NY to start a career in TV.
Guilfoyle is a former San Francisco and LA prosecutor, as well as a former Victoria's Secret. The twice-divorced Guilfoyle is a single mother of one son. She has been married twice, once to CEO Eric Villency and then to politician Gavin Newsom. Currently, the divorce is "uncontested", which means it's unlikely they will battle over assets or custody. She was also briefly romantically linked to former Trump communications director Anthony Scaramucci last fall, though he has since reconciled with his estranged wife.
The Post's Page Six claims that Trump Jr. and Guilfoyle have been dating for several weeks.
Guilfoyle is now the co-host of Fox News Channel's The Five, which airs weekdays at 5:00 p.m. ET.
Sources told TMZ that O'Day was telling close friends she had an affair with Trump Jr. "Additionally, she appears regularly on Hannity, among other programs".
