The youngest Trump child, Barron Trump, was thrust into the media spotlight during his father’s presidential campaign, and famously struggled to keep his eyes open during his dad’s victory speech on election night.

Barron, who turned 11 on March 20, is Trump’s fifth child, and only kid with third wife, Melania Trump. And Melania has said he really takes after Donald, perhaps even more than his grown-up children.

Barron has grown up inside Trump Tower where he has an entire floor to himself, including his own living room, mom Melania told Parenting.com. Barron and Melania have stayed at Trump Tower since Donald Trump became president, and according to a source who spoke to "Us Weekly," they may not be moving to Washington D.C. for a while.

The White House later denied the "Us Weekly" report, saying the two will move to D.C. after the school year.
