Those waiting with bated breathe for Prince Harry and Meghan Markle's engagement announcement will be glad to learn that she will be donning a wedding dress sooner than expected -albeit on the small screen.

Over the weekend, the Suits actress was spotted shooting scenes for her character Rachel Zane's wedding in Toronto – which will air in the next season of the paralegal drama. Her character will finally say 'I do' to fiance Mike Ross, played by Patrick J Adams.

According to witnesses, the 36-year-old divorcee got a practice run ahead of a potential future royal wedding by donning a £5,400 Anne Barge gown.

One person said on Twitter: "They are currently filming Suits in my hotel and I am freaking out!"

The information prompted many members of the online community to prob for more detail, with one suggesting: "So....hotel room filming? Or ballroom/function room filming, which would suggest wedding reception??? I'm intrigued!"

Although the TV wedding isn't the real deal, planning website and app the Bridebook told IBTimes UK that Markle is likely to opt for a complete couture wedding dress when her big day comes. She will avoid lace since it was the main aspect of both Kate and Pippa Middleton's gowns.

"We are confident that Meghan will strike the balance perfectly, looking timeless yet certainly fashionable too. Rather than opting for lace, which was the focus of Pippa Middleton's dress, we suspect she will choose a simple but beautiful bright white silk. Not only will this look beautiful because of her stunning colouring, silk also works well with striking folds and angles to add some modernity to the design."

This summer Markle, who was previously married to Trevor Engelson for a year in 2012, opened up about her romance with the fifth-in-line to the throne in a candid interview with Vanity Fair magazine.

"We're a couple. We're in love. I'm sure there will be a time when we will have to come forward and present ourselves and have stories to tell, but I hope what people will understand is that this is our time. This is for us," she said.
