Prince Harry and Prince William had a 'bit of a fallout' over Meghan Markle

Rewind to this time last year. Meghan Markle and Prince Harry's engagement just was announced on this day. They would take portraits, do their first joint interview, and Meghan would start doing events with Harry in the weeks ahead. She'd received an invitation from the Queen to spend Christmas with the royal family at Sandringham-something most significant others of royals, including Kate Middleton, do not receive until they marry into the family.
