There is no doubt that the Cumberb*****s, or Cumber Collective will go bonkers over this rumor.

Glamour Magazine reported last year that BBC series "Sherlock" star Benedict Cumberbatch and "Downtown Abbey"'s Laura Carmichael had hung out after a Lady Gaga gig at The Rodehouse in London. The two were seen "taking selfies" and having "deep conversations," prompting the rumor mill to deduce that the two were, in fact, dating. Despite being from different shows, it was most likely that the two had hooked up since they both have worked previously together in the John Le Carre novel-based thriller "Tinker Tailor Soldier Spy." Carmichael's character in the film, which is a MI6 agent, falls hard in love with Cumberbatch's closeted gay character.

The two are reportedly believed to have parted ways as there have been no sightings of the two together. And now, a gossio blog has claimed that the reason the two have split is because they do not agree on how they do things in the bedroom!

Crazy Days and Nights revealed in one of their blind items back in May this year that an actress from "Downton Abbey" went out with a foreign-born actor who has done mostly television work and is loved by every woman. The blog also went on and said that the couple had split because  "he went all Fifty Shades Of Grey on her," which had allegedly daunted her as "she is more of a turn off the lights and close your eyes kind of lover."

Although there were no other details provided, Celebitchy has picked up the blog commenters' deduction that the "foreign born almost A list" actor could be Benedict and the "Downtown Abbey actress" would be Laura. Yes, the man who plays everyone's favorite detective might secretly be a Christian Grey in the bedroom and Edith may not be into it.

Despite the fact that CDAN is not a reliable source, it seems it was every woman's fantasy coming true knowing the British bachelor does enjoy a little sex adventure once in a while. Moreover, ladies might be wondering why Laura wouldn't give in to his fantasies? Could it be that she identifies too muc to her character Edith, who is known in the show as demure and plain-looking compared to her sister? On the other hand, the actress herself is a lovely woman who has an eye in fashion reflected in her red-carpet appearances.
