Tom Hiddleston off the market? British actor Tom Hiddleston has been dating new girlfriend Jane Arthy since the beginning July and the couple seem to be getting more serious. Though It was recently rumored that Jessica Chastain was Tom's girlfriend in the beginning of 2013, but it is confirmed the actor is seeing Jane and has been since the beginning of the summer.

Tom's new girfriend Jane Arthy is a succesful music exec that might be just the kind of girlfriend Hiddleston needs to kick start his hopeful music career. Tom has always wanted to break into the industry and make an album and Jane's connections could be just what the British hunk needs to be successful.

However Tom and Jane might not yet be exclusive just yet. A third woman was added to the mix after the Avengers star was spotted getting cozy with a pretty brunette in the back seat of a black SUV.  

After his date with girlfriend Jane Arthy at the 2013 Wimbledon tennis matches, Tom Hiddleston was seen at London restaurant Nobu, but with a different, unknown woman who was gorgeous.

Tom and Jane, a record exec, watched the 2013 men's singles at SW19 to watch Andy Murray, his good friend. The pair were holding hands throughout the whole game that Murray wound up winning.  Hiddleston also tweeted about Wimbledon, including calling it the "best day ever." He didn't mention Jane Arthy, however, nor did he deny the rumors. However, he did tweet, "Andy Murray. You astound me. #wimbledon."

And as for Jessica; she is puzzled by the girlfriend rumors altogether.

"Why would they say that?" she told USA Today. "It's not true at all. It's funny, two weeks ago I was dating - I'm not dating.

"But there was an earlier rumor on Page 6 that I was dating [co-star] Edgar Ramirez. I love him, but he's just my friend."

Jessica Chastain does indeed have an undercover romance with fashion executive Gian Luca Passi and it is reportedly getting serious.

The 35-year-old Oscar-nominated Zero Dark Thirty actress  also rumored to have been quietly dating Gian, an Italian senior official for French clothing line Moncler, for some time now.

Apparently the pair are smitten with each other.

"They've been dating seriously for awhile now and Gian really likes her," a source told Us Weekly magazine.

It is said that Jessica is doing everything in her power to keep her relationship out of the limelight.

Her supportive beau is of the same mind and is willing to go out of his way to ensure their affair remains private.

When asked by American journalist Katie Couric on talk show Katie whether or not she had a boyfriend, the star gave a clear answer.

"I do . . . I have a rule that I don't date actors so he's not in the business at all . . . He's in the fashion industry," Jessica shared.

So we will wait to find out who indeed is the real girlfriend of Tom Hiddleston!
