Vanessa Trump reportedly used her kids to call out Aubrey O'Day over Don Jr. affair.

We've been hearing a ton about singer Aubrey O'Day's alleged affair with Donald Trump Jr. Now there's news of how Don Jr.'s wife, Vanessa, reacted when she found out, and it involves her using their kids to guilt O'Day. At that time, there were three of them — daughter Kai, now 10, and sons Donald Trump III, now 9, and Tristan, now 6.

After finding out about the affair via emails between her husband and O'Day, Vanessa Trump reportedly confronted O'Day by telephone, with Kai, who was five years old, on the line, too. A source told Us magazine, “Vanessa went crazy and was super jealous.”

According to an insider close to O'Day, the affair was very passionate. The source told the publication, "When it started, he and Aubrey were very serious all of a sudden. He told her 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."

When they met in 2011, O'Day was a contestant on Don Jr's father's show, Celebrity Apprentice, on which Don Jr. served as "advisor." His feelings for O'Day did seem real, according to another source, who told Us, “Don wanted to leave Vanessa for Aubrey, and told her he would. He fell in love with her."

But it wasn't just Vanessa who wanted the affair to end — Us reports that Donald Trump Jr's family, including his famous father, stepped in and urged him to break it off with O'Day and stay with his wife. Which is what he did, until Vanessa filed for divorce this month.
