Kristen Stewart Out With Justin Theroux? Behavior 'Surprising' Says Witness

Kristen Stewart was reportedly spotted enjoying a night out with actor Justin Theroux, who is the fiance of actress Jennifer Aniston, it has been claimed.

Theroux, 41, reportedly spent an evening with a friend at Hollywood's Chateau Marmont on Oct. 3 when Stewart, 22, randomly approached the actor before engaging into a long conversation, according to Star magazine.

The "Twilight" actress allegedly began speaking with Theroux prompting his friend to leave them alone together. The pair then spent approximately one hour together and at one point Stewart was even seen touching his hand, according to one eyewitness.

"It was kind of surprising to see, but she seemed completely relaxed," the onlooker reportedly told Star magazine.

The report follows growing speculation that Stewart, who was recently embroiled in a cheating scandal, may have since reconciled with her "Breaking Dawn" co-star Rob Pattinson, 26.

The actress, who has been dating Pattinson for three years, was photographed intimately hugging her married "Snow White and the Huntsman" Director Rupert Sanders, 41, in July. Photographs of their tryst immediately went viral on social networking sites.

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry," Stewart previously said in a public statement.

Pattinson was understandably left heart broken over Stewart's cheating admission and the actor reportedly ended their relationship days later, although this claim has never been verified.

The pair were photographed together in public on Sunday for the first time since Stewart's cheating scandal, where they spent time at the Ye Rustic Inn, a bar in Los Angeles' trendy Los Feliz neighborhood. The photos were reportedly taken after Stewart's alleged run-in with Theroux.
