With news of Benedict Cumberbatch's girlfriend allegedly joining him for dinner in Los Angeles last month, fans of the British star is in a clamor to know just what it is with this woman that made his heart flutter.

According to Latin Post, the 'Hobbit' star is better suited with a smart woman.

His sister reportedly spoke up about her brother's ideal type after the actor's split with fashion designer Anna Jones in 2012. Cumberbatch, according to his sister, is very well-read, therefore, only a girl with the same intellectual capacity would fit him.

"You have to be a pretty smart cookie to keep up with him. I think that is possibly why he has trouble with girlfriends," Tracy Peacock-Tabernacle told British newspaper The Sun via the Daily Mail. "He is such a lot like Sherlock-he is quick thing like him, but not harsh. He's incredibly well read. In comparison to some he is quite an intellectual."

With this tidbit of knowledge, is the quick-thinking star's rumoured girlfriend anywhere close to his sister's criteria?

According to Showbizspy, she just might be.

The new leading lady in Cumberbatch's life is reportedly not an A-list actress. She's not even part of the entertainment industry.

The mysterious lady reportedly "has quite a serious career" and she wants to keep her anonymity as long as possible.

Peacock-Tabernacle also noted that her brother would most likely be settling down with "someone not in the acting profession" in her past interview. He reportedly needs a woman who would be "happy to hold the fort while he went off and pursued his career."

Would this mystery woman be just the one to "hold the fort" as his sister pointed out? Will Benedict Cumberbatch's girlfriend be the one to make him hear wedding bells soon?
