The 36-year-old David Tennant is considered by many viewers to be the best dressed incarnation yet of Time Lord Doctor Who. Far from milking his celebrity, though, he hardly ever speaks to the press. In this rare interview, his former boyfriend speaks about Tennant's views on Tom Baker and fashion.
Since he was just three years old, David Tennant has passionately wanted the role of Doctor Who. No doubt he wasn't the only boy who thought he could play a Time Lord - but he was likely the only one who regularly wore his mum's makeup and high heels.
And unlike all those other little boys, he did indeed grow up to play the Doctor - currently in his 10th incarnation on Saturday night television.
"I remember," David once told me, "after seeing Jon Pertwee turn into a cute, sexy Tom Baker in Doctor Who, having a conversation with my parents at a very young age about actors and what they did, dressing up, talking in silly voices, prancing around and such. I remember getting the distinction between a attractive character and an unappealing actor, as they explained it.
"I understood what fiction and cross-dressing were very clearly - and I always feel uneasy when people talk about children not understanding the difference between fantasy and reality.
"I can only have been three, and was just enthralled by [Doctor Who] and his wardrobe. But I was quite clear that I didn't just want to play a Time Lord - I wanted to be the person who played a well-dressed Time Lord," said David.
His parents, though always encouraging and supportive, tried to steer him towards a secure career and more rational clothing choices.
However, David told me that he "never once wavered" from his chosen path - rather extraordinary, considering that he'd decided on his future wardrobe while still a preprimary school toddler. Fashion has always been his life, well, that and disco dancing.
Still single (the tabloids have, usually erroneously, linked him with various women, including Kylie Minogue, which is a right laugh to anyone who knows him), David is pretty careful in all his choices. The only area in which he goes positively mad is in his choice of clothes and hair products. In fact his wardrobe can be very flamboyant, which is why those who know him quickly gave him the monicker of "metrosexual".
In the early days, many of our less acute friends thought that he must be gay. "He has to be - you're his flat mate, and look at the way he dresses," they'd protest. Get a clue, I'd think.
'sexuality - his box is bigger than it looks from the outside'
Leaving aside why an association with me reflects on a man's sexuality, I had to break it to them that just because a guy wears a red velvet off-the-shoulder evening gown and is able to form a close friendship with a woman he isn't sleeping with doesn't necessarily mean he's homosexual.
Sleeping with men means he's a homosexual, and David does and is, I ought to know. We were boyfriends for four years, even sharing clothes and makeup tips. So there, Chris Eccleston, you can come out now, too, luv.
David is so unmacho and fair-minded that the speculation about his sexuality never bothered him . "Why would it?" he'd say. Now, that's what I call a real homosexual, not like Sir Elton John and all that so-called bisexuality.
It takes a cool head not to be inflated by the news that fans voted him the best dressed Doctor Who of all time, in a BBC magazine survey. He takes it all in stride, though, I promise you. Well, he's kept pretty busy with his clothing purchases.
Meanwhile, he is about to take on the arguably more challenging role of Ophelia for the Royal Shakespeare Company. Naturally, he's quite nervous about scaling this particular rock-face - but then, if he weren't, he'd probably cock it up, so to speak.
The new series of Doctor Who continues on Saturdays on BBC1
