Doctor Who gets sexier by adding an Avenger as a S7 guest star

A few days ago, we told you about four awesome guest stars who were set to join Matt Smith's Doctor and Jenna-Louise Coleman's Companion for some timey-wimey adventures on Doctor Who's upcoming seventh season in 2013. If you thought that was already brilliant, wait till you hear WHO will also be joining our favorite Time Lord for some time-traveling goodness.

Hint? She was a '60s British bombshell.

Dame Diana Rigg, who played the famous Emma Peel on The Avengers (that's the other Avengers) and also got famously hitched to James Bond in 1969's On Her Majesty's Secret Service, will appear on Who alongside her daughter, actress Rachael Stirling (Centurion, Snow White and the Huntsman).

Right now the BBC is keeping mum on the details, but Rigg and Stirling will play a mother-daughter duo, and their characters are said to be sharing a dark secret. Rachael Stirling called the episode ''funny and original.''

The script is written by Mark Gatiss (Sherlock co-creator and writer of ''The Unquiet Dead,'' ''The Idiot's Lantern,'' ''Victory of the Daleks'' and ''Night Terror'').

Diana Rigg said: "The first time Rachie and I will be working together is on an episode of Doctor Who specially written for us by Mark Gatiss. How lucky is that?"

If you recall from the previous post, it's also the ''historical'' episode David Warner (Tron, Star Trek V, Star Trek VI) and Liam Cunningham (Game of Thrones) will be appearing in, so we have high hopes for this one, as it's boasting some quality guest stars. (But when is it not?)

What do you think of this fantastic casting news?
