Hollywood stars Kristen Stewart and Nicholas Hoult were spotted at the MegaZip Adventure Park on Sentosa Island in Singapore recently.

Fans became excited as they spotted the two actors zip-lining and go-karting at the facility. Stewart wore a cap, a black T-shirt, shorts, long socks and trainers. Hoult was also wore a red cap, T-shirt and shorts for the occasion. Fans were delighted that the two agreed to pose for pictures and spent some time with them.

Enthusiastic fans posted their photos on Twitter and Instagram.

The co-stars are currently filming the upcoming science fiction film 'Equals' in Japan. The film's setting is the near future, where emotions like love, hate and envy do not exist, and all humans are equals. Stewart portrays the central character while Hoult plays her love interest, according to the Daily Mail.

"It's always a weird position to be put in any film where the director chooses two people and is saying 'Hey, potentially in this world I'm creating you two could fall in love," Hoult said about their roles.

Stewart, on the other hand, claimed her role was less problematic.

"I'm definitely not afraid of 'feels.' My life revolves around it actually. Finding the balance between the head and the heart is important but I've always been very driven by the gut. Every thought or articulated emotion starts in shapes and colors and putting your finger on that is cool, but it's not necessary," she said.

The film is scheduled to be released some time in 2015.

Previously, the actors were spotted enjoying "sushi dates" in Tokyo. The two also participated in the ALS Ice Bucket Challenge together, reported Yahoo!

At the moment, Hoult is currently single, after his recent breakup with 'X-Men' co-star, Jennifer Lawrence, and Stewart's most recent romance with 'Twilight' co-star, Robert Pattinson, has ended.
