Trump told Don Jr to 'cut it out' and stop cheating on his wife while she was pregnant: report

President Donald Trump advised his son to not cheat on his wife while she was pregnant and to save his marriage, reports Business Insider.

According to the report, Donald Trump Jr. cheated on his wife with singer Aubrey O'Day, a contestant on "Celebrity Apprentice," for months while his wife, Vanessa, was pregnant with their third child, leading his father to attempt to intervene.

The pair began their relationship in late 2011 as the taping of the show was concluding, reports Us Weekly.

"When it started, they were very serious all of a sudden," explained a source. "He told her it was over with his wife, that they were separated and he didn't love her. … Aubrey fell for him hard. She thought they were going to be together for real."

Another source claimed Don Jr. told the singer his marriage was "already in the process of dissolving," and that he was confronted by his wife when she found emails between the two.

According to Page Six, Trump -- who reportedly had an affair with adult film star Stormy Daniels while his wife was pregnant with son Barron -- stepped in and told his son to "cut it out."
