Bethan Britton Age: 28 Miss Britton is a Contracts Assistant at BBC South Wales.
The striking blonde caught Mr Tennant's eye when she made a visit to the set of the Sci-fi show late last year.
Miss Moffett’s father Peter Davison, in turn, had played the fifth Time Lord.
He said: ‘I suspect that, crucially, Georgia wasn’t overawed by David.
Traditionally a man with an eye for blondes, Mr Tennant made a departure from type when he dated Miss Fava for a few weeks in April.
The exotic brunette helped him celebrate his birthday and the pair were spotted on a string of romantic dates in Cardiff, including a concert where co-star John Barrowman was performing.
Before the wedding, a friend said: ‘David and Georgia can’t wait to get married, they are madly in love.
They've been dating for a year and a half, but David Tennant and Georgia Moffett are keeping their romance alive with regular nights out.
The couple struck up a relationship just a couple of months after his split from long-term love actress Sophia Myles.
She still lives at her parents house on the outskirts of Cardiff so much of their four month relationship was spent at his city flat.
Tennant is almost 15 years her senior but her friends say that Moffett is more mature than her age, particularly as she is a single mother to six year old son Tyler.
Jennie Fava Age: 27 Miss Fava is second assistant director on the latest series of Doctor Who, but also worked on shows such as Extras and The Chatterley Affari.
