Kristen Stewart is said to dating her "Equals" co-star Nicholas Hoult. The two are reportedly inseparable and have been spotted spending lots of time together.

The duo sparked dating rumours when they were first spotted on a sushi date in Japan.

"Kristen and Nick are inseparable. They are constantly hanging out together when they aren't on set. They've really bonded with each other and are like best friends now. It wouldn't surprise any if us if it turns into something more serious, something romantic," a source told Hollywoodlife.

The two are doing a lot of things together, according to reports. They took the ALS Ice Bucket challenge together and also went zip lining in Singapore.

It's also been reported that Stewart usually calls her friends to stay on the films set but she has apparently stopped calling anybody.

"When Kristen is on location for long periods of time, she usually has a good friend come stay with her but not this time cause she has Nick," the source revealed. "They love playing practical jokes on the cast and crew, playing pool, just exploring and hanging out."

It is reported that Stewart and Hoult bond well, as they have many things in common like playing pranks and were spotted playing games together like pachinko-a really fun kind of arcade game in Japan.

The representatives of Hoult and Stewart are yet to comment on the link-up.

Stewart dated Robert Pattinson before breaking up after her relationship with her "Snow White and Huntsman" director Rupert Sanders went public. Pattinson is said to be dating FKA Twigs currently.

Hoult was in a relationship with Jennifer Lawrence but they split a few months ago. Lawrence is said to be dating Chris Martin.
