Vanessa Trump has filed for divorce from Donald Trump Jr. after 12 years of marriage. Page Six revealed that Vanessa filed on Thursday, March 15, in Manhattan Supreme Court. The pair made headlines back in February after Vanessa opened up a suspicious letter containing an unidentified white substance that was mailed to their apartment in New York City. Donald Jr. and Vanessa, both 40, started dating shortly after they met a fashion show in New York City in 2003.
