While other celebs tried to be super cryptic about the date, Olly jumped straight in and tweeted:

"The big day for Marvin & Rochelle has arrived!! Looking forward to it! Got me 'whistle & flute' pressed & clean".

We think this might just make us more excited than the Olympics Opening Ceremony!

This is probably the biggest celeb wedding of the year and loads of our fave celebs are expected to be at the church ready to chuck confetti over Rochelle.

Fearne Cotton, Pixie Lott, Alexandra Burke to name a few.

We wonder who is best man? We hope it's Aston — we reckon he would do a brilliant speech!

However, we already know who will be bridesmaids, Rochelle's fellow Saturdays of course.

And we think Frankie and Mollie might be a bit over excited about their super important role, judging by these rather LOLsome tweets the pair exchanged yesterday.

The girls announced they were heading off on a 'road trip' before tweeting they were in a hotel.

Now, unless they were on a romantic mini break we knew this could mean only one thing: Rochelle's wedding!

Oriste confirmed things after he tweeted: "A wedding is happening! Ori x" from the official JLS account.

The girls were getting up to some mischief ahead of their bridesmaids' duties today.

Mollie tweeted: "Sharing a bed with @FrankieTheSats...apparently my leg is "over the line" in her half!!! Why did I get stuck with her ;-) xxx"

Frankie replied, simply with "Spoonage".

Mollie later posted the message: "Stop coming onto me! I have standards!! X" to her band mate.

Honestly, we wish we were in a girl band — hanging out with your best mates doing what you love? Not bad.
