They laughed and joked as they filmed the Christmas Special - after a year enjoying their own space.
Billie, 26, took a break from playing side-kick Rose to become a mum to Winston, now seven months old. And she filmed the third series of Secret Diary Of A Call Girl.
An onlooker at the south London set said: "Billie and David were joking about and seemed delighted to be working with one another again.

"They've got a natural chemistry. They get on so well."
The Christmas special, featuring The Doctor's old adversaries The Ood, will be 38-year-old David's last but one appearance as the 10th Time Lord.
He announced last year that he will leave the BBC show at the end of 2009 after completing three full series.
David took over from the previous Doctor Christopher Eccleston in 2005. David's final episode will be aired on New Year's Day, when he hands over to Matt Smith, 26.

It's great to see David and Billie back together! I bet they missed each other loads, lol x I think the theory of his song is ending... is in series 4 when River Song said shes seen the Doctor before and goes through her diary of dates for things they could do it's like dates like shes his girlfriend but the doctor dosen't know that yet. the whole thing about her having a sonic screwdriver and "his rules" for not looking in the diary is because it could be there married future together. also, proper Dave mentions it when they were trying to work out what going on he says "your'e standing their like an old married couple!" and the final thing she know his real name.

I think the ood is ood segma. Ood Sagma was in Pllanet of the ood in series 4. And he said ''your song is ending'' and carmen (a lady on the bus) in planet of the dead also said ''your song is ending sir''
so maybe the ood is back 2 tell him something like that.

not sure about the ood, i am so goin to miss david tennant he is just amazing he really plays the role well im sure matt smith will be great but he has some boots to fill.
love billie piper in this so glad she is back, although everyone got together in journeys end and not looks like they r gettin back together now i think the only appropriate way for david to leave the show is for everyone to be there especially rose!
cant wait to see what happenss!! eeeek x

So happy to see Rose back. I desperately want a better end to the Rose/Ten love story than we had in JE. I mean, come on, who takes an identical twin as a substitute for the person they love? And Ten 2...he's part Donna...he killed the Daleks (a good decision, in my book...but whatever) that wasn't a decision that Ten would have made. So, why, exactly, do people think he would just automatically suit Rose? JE's ending makes no sense at all.

Princess 40. I am one of the dreaded Roseshippers. I love her chavoliciousness.
Thing is, maybe this ending will be better than JE. Just make it more believable and I can live with it fine.
The nature of Who is change but at least make the ending right/acceptable/believable.

Great to see Billie back but I wonder what will happen to the duplicate Doctor...was hoping they'd bring him back later so that David Tennant could return. And...I'm not liking the idea of the Oods returning...they were great to begin with but they've been used enough already, and it would be immensely dissapointing to see David Tennant being killed off by an Ood. I thought the Master was returning; it would be a more glorious death than by Ood.

it looks like he's going back to before he met her,
so it looks like she won't be there for the regeneration

Well I think its brill to get all the team back, I am sooo going to miss David Tennant as the Doctor I wish him well for now and his future, can not wait to see Dr Who later on this year! Yipee!!! xx

Billie Piper looks great, but oh no---for God's sake, now we'll never hear the end of those inane little prattering Rose shippers--thanks for nothing!
So, even tho' I'm thrilled to bits to see Donna, Wilf, et.al, again, basically, Tennant's finale is going to be sort of a re-hash of last year's finale, a "let's-stuff-everyone-into-the-Tardis-to-pump-up-the-ratings" bit?
Love Davie's writing, but...for once I have my reservations...hope it won't mess with my suspension of disbelief.

By becky.. Posted May 17 2009 at 4:25 PM.

so she will be there for the re-genration? makes sense that she was there for Davids begining and now his end.
i wasnt to bothered about the speicals, but hereing Billie is back, i cant wait

YOU broke the agreement promising not to mention that the Ood would be involved.

Bored, bored, bored of the past characters and monsters. Get new ones, please. It's all predictable, we all know what will probably happen. Is Russell trying to break his own record to have as many past people in one episode like he did for the last two of series 4?

NOT HAPPY to see you have broken the agreement made on set last night!
