Many factors — including reports of messaging a model and alleged controlling, tightwad behavior — have been cited as reasons for Donald Trump Jr.‘s impending divorce from wife Vanessa after 12 years of marriage and five children. Infidelity may also be to blame, according to new reports.

Page Six has claimed that the eldest son of President Trump had an extramarital affair with singer Aubrey O’Day, formerly of the girl group Danity Kane, in late 2011 after her appearance on NBC’s Celebrity Apprentice. Vanessa Trump was pregnant with the couple’s third child at the time of the rumored fling, which sources tell Us Weekly ended in March 2012 after Mrs. Trump reportedly found incriminating emails between her husband and O’Day.

“When it started, they were very serious all of a sudden,” a source told the magazine. “He told [O’Day] it was over with his wife, that they were separated and he didn’t love her — all of that stuff. … Aubrey fell for him hard. She thought they were going to be together for real.”

Though O’Day has yet to confirm the affair, she may have dropped hints along the way. Us Weekly reports that the pop star tweeted her disapproval of Donald Trump’s presidential victory in 2016, calling him a “lying, abusive piece of trash” and adding that she had a story “worth millions” that “doesn’t hurt me, it hurts America.”

Vulture has also speculated that O’Day’s song 2013 “DJT” — Trump’s initials — may have been inspired by her rumored former paramour, as it describes pining for a man who leaves to return to his real life.

In the meantime, O’Day has been targeted by trolls since the reports broke Monday evening, shortly after she posted this Instagram.

Though much of the vitriol has been targeted at Trump Jr., many abusive comments and “Tramp and the Trump” references have come O’Day’s way on social media:

“DONALD TRUMP JR!!!! REALLY? Oh well hopefully you had baby wipes on hand after banging that greasy-looking motherf*****.”

“Don’t drag Aubrey O’Day for sleeping with Trump Jr. while he was married. Drag her for sleeping with him period.”

“Did you have [an] affair with Donald Trump Jr.?!?! His wife was pregnant!!”

“Eww you had sex with a Trump?”

“Aubrey O’Day has always been a no-good slut AND he’s who he is, soooooo worthless both of them.”

Others stood up for O’Day, and shifted the blame to Trump Jr.

“I need y’all to stop slut-shaming Aubrey O’Day and calling her a skank and a whore,” one Twitter user argued. “SHE did not stand before God and everybody and recite marriage vows to Vanessa. Donald Trump Jr. did. HE made the choice to dishonor his wife. HE is the skanky whore.”

And many are calling on the singer to share her side of the story, noting a previous tweet in which O’Day claimed not to have signed a nondisclosure agreement. Could a Making the Band star be the unmaking of the White House?
