This should be awkward.

During what seemed to be a successful visit with UK Prime Minister Theresa May at the White House Friday, Trump announced he had accepted an invitation from Queen Elizabeth II for a state visit later this year with first lady Melania.

But Trump's tweeting past might make the royal visit trip slightly uncomfortable. More than four years ago, Trump tweeted out some thoughts on Kate Middleton sunbathing in the nude and his thoughts on her looks.

Who wouldn't take Kate's picture and make lots of money if she does the nude sunbathing thing. Come on Kate! — Donald J. Trump (@realDonaldTrump) September 17, 2012

Kate Middleton is great—but she shouldn't be sunbathing in the nude—only herself to blame. — Donald J. Trump (@realDonaldTrump) September 17, 2012

Back in those pre-Trump presidency days of 2012, Trump wasn't commenting on any old celebrity caught in a nude photo leak — Middleton is the Duchess of Cambridge aka the wife of Prince William whose grandmother is Queen Elizabeth.

Like we said, awkward.

The sunbathing incident Trump was tweeting about refers to photographers, who are now on trial, who allegedly took photos of a topless Middleton. The photos were then leaked to the press.

Hopefully the royal meeting goes better than Trump's comments Friday to the British journalist from BBC News at the joint press conference.
