If you haven't heard of Aubrey O'Day, the popstar-turned-Playboy model-turned reality starlet, continue reading. You're about to be seeing a lot of the woman who reportedly broke up Donald Trump Jr's thirteen year marriage.

Irish American Aubrey O'Day has been linked to the President's eldest son, days after his wife of 13 years filed for divorce.

A song released in 2013 resurfaced this week. The track, "DJT", featured singer O'Day pretending to talk on the phone with her jilted lover as they broke up.

Unsurprisingly with its title, whispers of a torrid affair between O'Day and Trump have sent the rumor mill into overdrive.

Here's what you need to know.

Aubrey O'Day and Donald Trump Jr met while on the set of The Celebrity Apprentice

Around 2013, a source told US Weekly that former Danity Kane star O'Day had a dalliance with Trump Jr. The rumors were quashed at the time by Michael Cohen, the notorious personal lawyer of President Trump, who called the publication at the time threatening legal action.

Vanessa Trump was pregnant while O'Day and Trump Jr's affair allegedly took place

According to Page Six, Trump Jr told his wife that he planned to leave her for O'Day. Vanessa was pregnant with the couple's third child, Tristan, at the time.

The source told the outlet that Trump Jr “pursued [Aubrey]. It was him who chased her,” said a source familiar with the situation. “He told her that his marriage was already in the process of dissolving. I think his marriage to Vanessa was over long before Aubrey came along.”

Donald Trump (POTUS) reportedly said O'Day wasn't sexy enough while she competed on The Celebrity Apprentice

According to O'Day, the host told producers to tell her to up her sex appeal.

“There were two female producers that came up to me, pulled me aside and said, ‘You’re running circles around everyone. We didn’t expect that from you,’ ’’ she told TV host Andy Cohen on his “Then and Now’’ show in May 2017.

But then the women said, “Bottom line, ‘Trump doesn’t think you’re pretty,’ ” O’Day told the host. “ ‘If you want to stay in the game, you need to follow these simple rules.’ And the rules were: Start parting my hair down the center, wearing it straight and pushing my t*ts up in tight outfits.”

She was ultimately "fired" during the penultimate episode.

Aubrey O'Day got her popstar start thanks to P. Diddy aka Sean Combes

O'Day was selected to be in a made-for-TV band, as P. Diddy chose her to be the lead singer of the short lived group Danity Kane while filming MTV's "Making the Band" in 2005.

The band had a couple of hits, before O'Day was fired by P. Diddy in 2008.

"I got love for Aubrey. I don't have any beef with her," he said at the time. "I just want to work with the young lady that I signed, not the person that fame has made her."

Already a fixture in tabloids and gossip magazines, the next year O'Day was selected to pose for Playboy magazine. 

Aubrey O'Day previously dated Jersey Shore's Pauly D

The Playboy model had a year-and-a-half romance with the infamous Jersey Shore "Guido" and DJ.

They met while filming the E! show, Famously Single, and confessed their undying love for each other frequently during their tumultuous on-off relationship.

“We’re looking forward to the next steps,” Pauly D aka Paul DelVecchio said during their good days. “She’s the one for me, so I’m looking forward to the next steps and waiting for the right moment to make all that happen.”
