Today marks the biggest political day in modern UK history, as Scotland votes on whether it wants to remain a part of the United Kingdom.

With such a seismic news topic underway, a whole host of our favourite celebs have been weighing in on their thoughts ...

I know I don't live in Scotland. But I would be sad if we don't stay together. I always like the feeling of being united.

Big day in Scotland tomorrow #indyref. My head says no and my heart shouts it - but whatever happens, I hope we're all friends by Saturday.

And while it may not be on Twitter, we thought we'd give a shout-out to David Beckham for his rather heartfelt plea for the UK to stick together. Take it away, Becks...

“I took as much satisfaction in seeing Sir Chris Hoy or Andy Murray win gold as I did watching Jess Ennis and Mo Farah do the same in the Olympic Stadium”, Becks said. “The decision on whether to leave our shared country is, of course down to you, it is not my intention to tell you what to do. Nevertheless, that decision will have a huge effect on each and every one of us in the United Kingdom. We want to let you know how very much we value our relationship and friendship. Of course regardless of your decision that will never change, however, my sincere hope is that you will vote to renew our historic bond which has been such a success over the centuries and the envy of the entire world. What unites us is much greater than what divides us. Let’s stay together."
