Meghan Markle's Suits co-stars are on their way to London!

The best thing about the bride being a (former) Suits actress is that along with all the Royals going to the wedding; there'll also be a load of celebs. And American celebs at that.

The meeja has spent the last six months speculating which stars are going to be on their very best behaviour in Blighty this weekend. Serena Williams might come! The Spice Girls will almost certainly be there. And, it seems like Meghan's Suits co-stars are also making their way across the pond for some Wedding of the Year action.

How do I know this? Instagram stalking, of course! The only other way to indicate you're on the way to the wedding is to, eh, stage some paparazzi shots. *insert see no evil emoji*

Gabriel Macht, who plays Harvey Spector on the show, is married to Jacinda Barrett, an actress you might recognise from Bridget Jones: The Edge of Reason. She posted a pic of herself and her son outside Buckingham Palace, suggesting only one thing. Right?

THEN, Sarah Rafferty aka Donna posted an Instagram pic from Paris, which is just a train ride from London. So.

That's all the evidence we have for now. But this is our life now. We will be eating, sleeping and breathing Royal Wedding malarky and we're not ashamed of it. Keep up with us on site, and on Instagram and Twitter, where we'll be getting in on the action live all day.
