Susanna Reid joked that the ponytail made David Tennant look like a woman.
Say what? Obviously, she never sensed the sexual electricity between Tennant's Dr Who and Rose (Billie Piper) which held fans enraptured for a season or two.
Understandably, the Scottish actor looked slightly taken aback by the joke, by recovered well by telling her: 'That's slightly what we were going for.
'I'm playing Richard II at the RSC and there's a slightly androgynous quality we were slightly pursuing.'
David went on to discuss life as both a stage and screen star, what with his critically acclaimed turn in Broadchurch as well as wowing audiences with the Royal Shakespeare Company.
'They're quite different jobs,' he explains. 'The pacing of your day is very different. The theatre is all about three hours of intensive work at the end of the day whereas filming is sort of about finding those intense moments in a day with lots of gaps in between, but that's part of the joy for me.
'The varieties is one of the great joys of this job'.
But while he was chatting about new legal thriller "The Escape Artist," sci fans would be aching to see him in the Doctor Who 50th anniversary special, reprising his role as the tenth Time Lord.
But even though he passed on the reins to Matt Smith - now set (thank God) to be replaced by Peter Capaldi - David says the attention is still there.
'It doesn't really stop,' the actor said on BBC Breakfast. 'Doctor Who doesn't go away and people always want to know about it. Even people who don't watch the show are interested.'
