From Tony to Timelord!

I've said it before, and I'm sure I'll say it again. One of the best things about working on Newsround is the range of things I get to do. It means that you never get bored, and every day is different.

Today's a great example of that. This morning I presented a special event where children got to question the Prime Minister, and other top members of the Government about what they're doing to tackle climate change.

It was great meeting so many kids who care so much about the environment, and who aren't afraid to tell politicians what they think they should be doing.

The outside of No 10 Downing St looks like an ordinary house, but inside it's massive. I remember thinking as I walked about that it was like a Tardis inside.

Which leads me nicely to the second part of my day. Another fab thing about working at the BBC's TV studios is that you bump into all sorts of interesting people. And this afternoon I was on my way to get a late lunch when I spotted David Tennant - Dr Who himself - being interviewed by a TV crew.

Despite being one of the famous faces on TV, David's always really friendly and he bounded over to say hello. And we had a quick chat about the new series.

He also gave away a few snippets about what he was doing here. He was filming for the fab behind the scenes show Dr Who Confidential which comes on BBC3 straight after each episode. In fact, he was doing the whole episode himself - and it was all about the 10th story in the new series which is called Blink.

The team filming with David, from the camera crew to the boss, Gillane, were all really great as well - I love chatting to fellow Dr Who fans. I tried to overhear a bit of what David was talking about during the filming, but could only catch a few snippets. Which I'd better not repeat here.

David's been filming since last summer, and revealed that filming will finally finish at the end of this week. But he did promise me that series 3 will be 'bigger and better than ever'.

UPDATE: Well, I thought I'd finished writing this blog. But after presenting the programme on BBC One at 5.25, I was wandering back to the Newsround office, and who should I bump into, but the Head Writer of Dr Who, Russell T Davies! And he was with a writer called Gareth Roberts, who's penned the second story in the new series - The Shakespeare Code. Naturally, I couldn't let them go without getting some gossip. So they mentioned that they thought I'd especially like the Shakespeare Code, because there's a mention of the new Harry Potter book in there. Now, I really can't wait!
