The Personal Shopper star and Victoria's Secret model Stella Maxwell are officially dating.

The pair were recently spotted spending time together in Savannah, Georgia, where Stewart has been filming a new movie about Lizzie Borden, who was infamously accused of murdering her father and stepmother with an ax in the 19th century.

The actress and model seemed to be enjoying their time together walking the city streets and laughing together on set. Stewart was also photographed with scraped knees and a bruised face, although it is unclear how she sustained the injuries.

"Kristen also seemed very happy with Stella around," the second source continued. "They weren't affectionate, but definitely acted very friendly and like they had the best time hanging out. Stella seems very easy going. She is always very smiley and has a cute personality."

Stewart and Maxwell were first seen together at the Met Gala earlier this year, and were pictured leaving an after party in the same car.

Kristen - who was previously in a relationship with Robert Pattinson for five years - recently admitted she isn't "ashamed" of her sexuality.

The Equals actress admitted she is more open about her personal life now she's in a same-sex relationship and feels much happier that she is being less closed off to people.

She said: "When I was dating a guy I was hiding everything that I did because everything personal felt like it was immediately trivialized, so I didn't like it.

"We were turned into these characters and placed into this ridiculous comic book, and I was like, 'That's mine. You're making my relationship something that it's not.' I didn't like that.

"I was like, 'Actually, to hide this provides the implication that I'm not down with it or I'm ashamed of it, so I had to alter how I approached being in public. It opened my life up and I'm so much happier."
