Kristen Stewart maybe madly in love with Robert Pattinson, but we are smelling a possible scandal as the "Twilight" starlet is set to star with a sexy British actor, who is just like her hunky beau.

Jim Sturgess, Stewart's new co-star in the upcoming film The Big Shoe, is a British actor and musician, who is said to have great chemistry with Kristen.

In the Steven Shainberg-directed film, 31-year-old Sturgess plays a gifted shoe designer, and 22-year-old Stewart his muse.

Fresh off Robsten's reconciliation following Stewart's cheating scandal with Rupert Sanders, Robert Pattinson may get jealous over another British heartthrob who may get in the way of the "Twilight" co-stars and off-screen couple.

What may get Robsten fans more nervous is the alleged chemistry between Kristen and Jim.

“Jim was in town last week for pre-production meetings on his new movie with Kristen and they got along really well,” one insider told Hollywood Life.

“Jim is super shy and unassuming, he’s actually a lot like Rob – really polite and he has the cutest British accent. It’s quite posh, just like Rob’s. Jim and Kristen have major chemistry, they really seem to click. They were talking up a storm about England and how bad the weather is there. They talked about their dogs and music. Jim is a really talented musician, so they connected on that a lot too.”

And that comes with no surprise as the two British hunks share a handful of similarities.

Sturgess came to the Hollywood scene in Julie Taymor‘s 2007 musical Across the Universe, according to Hollywood Life.
The actor was also acclaimed for his musical talent. Jim has been composing songs since the age of 15, and has written some for his films.
Rob too wrote two songs for the "Twilight Saga" soundtracks, the site points out. Both Londoners are handsome and sexy, and are equipped with guitar and piano skills.

No wonder the awkward actress opens her heart to Sturgess.

Rob's potential contender, however, is not single.

Sturgess is in a relationship with Mickey O’Brien, keyboardist for the band La Roux.
But who knows - Sanders was also married to a sexy model and actress Liberty Ross.

"There wasn't any over the top flirting or anything, but Kristen was enjoying herself, she kept touching her hair and she was laughing a lot. Jim has a girlfriend and Kristen is back with Rob, so it's totally professional between them right now," the source added.
