Rumours are rife that "Twilight" actress Kristen Stewart is dating Jennifer Lawrence's ex-boyfriend Nicholas Hoult.

Hoult and Stewart reportedly became close during the filming of "Equals", a futuristic romance story where the duo play lovers. Filming took place in Japan, not long after Hoult called it quits with Lawrence, and Stewart and Robert Pattinson broke up.

 According to the actors, being away from home helped them get over their heartbreaks.

"It was nice to feel so isolated from everything, from our lives," Hoult told The Daily Beast. "It's often the way we are on location, but particularly in this movie it was very intimate, and a nice environment to be in."

"It was incredibly painful," Stewart added. "It was a really good time for both of us to make this movie. We all felt akin by how much we've been through, and to utilize that is so scary."

Neither Hoult nor Stewart has yet admitted to being romantically involved with each other. Hoult was romantically linked with Dianna Agron earlier this year, and Stewart was said to be in a relationship with Alicia Cargile. An OK! Magazine report even claimed that Stewart and Cargile were married.

Apparently, someone attending a party for "American Ultra" premiere on 18 August in Los Angeles asked Kristen how her night was going, to which she replied, "I miss my wife!"

"When I congratulated Kristen on being married, she gave me a quirky smile and coyly said 'thanks!' and then ran off to celebrate with friends and costars, who were hugging and congratulating her all night," the eyewitness told the magazine, reported HollywoodLife.

However, this hasn't stopped Hoult and Stewart from getting cosy with each other whenever time permits. The pair was spotted in high spirits at the Venice Film Festival in September, and they were also seen "cosying up" at a film bash in New York in October 2014.

According to the New York Post's Page Six column, Stewart and Hoult "stuck together" all night during a Cinema Society event for "Clouds of Sils Maria."
