Prince Harry secretly visited the set of Suits, his girlfriend Meghan Markle's television show, on Wednesday when he quietly flew into Toronto a few days early. He apparently met the cast and crew of the US legal drama and proudly watched Meghan in action.

'Everyone was so excited,' a source said. 'He was super low key, met some crew and was so happy to watch his lady.'

Prince Harry arrived at the York Lion Stadium in Toronto for the Invictus Games on Sunday. Although hopes were high that he would be accompanied by Miss Markle, the royal arrived at the York Lions Stadium alone.

However, the previous evening he and Miss Markle had appeared at the same official event - the opening ceremony for the games. Meghan sat next to Markus Anderson, her 'best friend' who introduced the pair last year, while Prince Harry was 18 rows away. Instead of his girlfriend, Harry was seated next to First Lady Melania Trump in a VIP box.

Her low key presence marks the first time she has joined the Royal for an official event and will intensify speculation that an engagement announcement is imminent .

The distance did nothing to dampen the actress's excitement. She beamed as Harry gave an inspiring speech on stage during which he told the 550 athletes gathered: 'You are all winners. You are Invictus.'

Intriguingly , as she is not entitled to British tax-payer funded police protection, one of Harry's Scotland Yard security officers could be seen hidden away in a stairwell close to where Miss Markle was seated. Presumably he had been stationed there to whisk her away as soon as the opening show had ended.
