Deathly Hallows: Ricky's Harry Potter premiere diary
Ricky meets Potter cast and fans at Deathly Hallows world premiere
We sent Ricky to the world premiere of Harry Potter and the Deathly Hallows Part 1 to report for Newsround - and keep you up to date with everything that was going on.
It got pretty hectic at times, but you can find out what was going on by reading his updates from London's Leicester Square!
So that's it. All the celebs are inside the cinema now. I feel a bit sad knowing there's just one film left!
Rupert Grint spoke to me before he headed in. He's thinking about arriving in his ice cream van next year for the summer release of Deathly Hallows Part 2. I hope I'll be on the red carpet to see that!
By the way, if you missed it earlier, check out what Rupert, Emma and Daniel looked like at the premiere of the FIRST Harry Potter film way back in 2001!
What the Daniel, Emma and Rupert looked like nine years ago!
Just met Emma Watson, her brother Alex, AND Daniel Radcliffe!!
Emma said she's really relieved it's not raining! But she has a big coat on just in case...
Daniel told us that Deathly Hallows is author JK Rowling's favourite film by 40 leeks - but I have no idea what that means!
Just spoke to Harry and Tom from McFly. Tom says he's the biggest Harry Potter fan!
Also chatted to Matt Lewis, who plays Neville Longbottom. He hasn't seen the film yet but said he's really excited and can't wait!
Just chatted to Paije and Aiden from The X Factor.
Earlier this week, Rupert Grint told me that Paije is his favourite in the competition!
Watch Rupert Grint's chat with Ricky
Getting busy now. Cher Lloyd, Katie Waissel, Wagner and all the X Factor acts are turning up.
One Direction couldn't stop to chat, but they did say they love Newsround!
Still waiting for celebs to reach us, so having a quick chat with Hacker while we wait!
Tom Felton and Daniel Radcliffe just arrived to MASSIVE cheers from the crowds.
Emma and Rupert are still signing autographs and chatting to fans. No sign of any of them on our bit of the red carpet yet.
Just finished my live report from the red carpet.
Rupert Grint and Emma Watson arrived just as we went on air! We haven't missed them though. I'll be trying to grab a chat with them and loads more stars on the red carpet - and you'll be the first to know how I get on.
Watch again: Ricky's report from the red carpet!
Just met some fans who've been here since 8am - that's before I was up!
Spoke to one guy from Peterborough who said he's going to cry because he's so emotional. There are fans from all over the world here, including Poland, Spain and Portgual!
Guess what. It's raining everyone. Here we go again. Trying to stop the camera from getting wet.
Good news though. CBBC's Hacker is here!!!
Just checked in. We have to get special passes so we can do all the filming and interview the stars.
I'm in the car on the way to Leicester Square. Feeling pretty excited.
Right now I'm reading all the latest Potter headlines on my phone - to make sure I know exactly what's going on...
Ah! I can see Leicester Square now. Got to go!
So the clock is ticking away. I'm sitting in the Newsround office getting ready for the Harry Potter premiere.
I actually feel pretty sad that after this premiere, there will only be one more left.
I've interviewed Daniel, Rupert and Emma four times now and I'd like to think we've been pretty good to them at Newsround. Lots of you guys have watched them grow up on our programme and I'm chuffed to be able to bring you all the fun and glamour from tonight's event in Leicester Square.
I'll be sending the Newsround web team live updates when the cast arrive and the fans go wild! Check back soon!
