Royal baby watch
Before Britain's Catherine, Duchess of Cambridge, gave birth to her second child in 2015, royal baby mania ramped up on the streets of the UK.
Die-hard royal fan John Loughrey, aged 60, has spent four nights sleeping on a bench across the street from the Lindo Wing of St Mary's Hospital, where Kate is scheduled to give birth.
Decked out in the Union Jack, "Union John" here is determined to be one of the first to know when the time comes.

With a homemade poster -- bearing the faces of Prince George and Prince Harry -- these royal family enthusiasts got us thinking about the line of succession.
The newest royal will be fourth in line to the British throne, bumping Prince Harry yet again. Harry got bumped to fourth in line when George, his first nephew was born.

Royal fan John Loughrey poses for photographers outside the Lindo Wing of St Mary's hospital in central London, April 17, 2015, where the Duchess of Cambridge is expected to give birth later this month.
He wears a Union Jack hat, adorned with numerous pins. Most of the buttons are Queen Elizabeth-centric, bearing phrases like "Long live the queen." He also, however, sports a button which reads, "Don't take yourself too seriously."
...An important thing to remember when you're wearing this sort of outfit.

Doppleganger of Wales
This man celebrates the impending royal birth with British baby brand Philips Avent, as part of their royal look-a-likes event.
Judging from his t-shirt, he's clearly under the impression that Prince Charles is his doppleganger. But we think it's a bit of a stretch.
