In the celebrity world, dating rumors are almost part and parcel of a celebrity's existence. There are rumors that eventually end up being the truth while more rumors have no specific basis and end up being just idle gossip or a marketing ploy. Regardless, rumors are one sure way to catch the public's attention.

According to International Business Times, Benedict Cumberbatch, the star of "Sherlock," is currently off the market with rumors of him having a girlfriend whose identity he is working hard to keep secret. It seems that his current girlfriend is not an A-lister and she has a serious career and is not in the public eye, hence the secrecy.

Based on what his sister said after he split up in 2012 with Anna Jones, a fashion designer, the right woman for her brother should be just as smart as him. She said that her brother is well-read and an intellectual and, just like his character Sherlock, is a very quick thinker.

Benedict Cumberbatch has yet to come clean about the rumored girlfriend but his sister is already hinting that wedding bells might ring soon. According to Tracy Peacock-Tabernacle, one of the regrets of her brother is that he has not found the right person to settle down with and she thinks that someone not from the same industry would be a good match for her brother. She says that he needs someone who will gladly hold down the fort while Benedict goes off to pursue his career.

Prior to his short romance with Anna Jones, Benedict Cumberbatch had a long relationship with screenwriter and actress Olivia Poulet. They were college sweethearts and he revealed in his Vogue interview last year that he will always have warm feelings for her. He was quoted as saying that he will always love and adore her.
