Kristen Stewart spotted on date with Stella Maxwell

Jan. 31 (UPI) -- Kristen Stewart was spotted on a date this week with rumored girlfriend Stella Maxwell.

The 26-year-old American actress was seen holding hands with the Belgian-Irish model, also 26, during an outing to Knott's Berry Farm theme park Sunday in Buena Park, Calif., according to People.

The Twilight star was all smiles in a black jacket, jeans and grey t-shirt as she strolled with Maxwell in the park. Entertainment Tonight reported the pair rode the Boomerang rollercoaster and enjoyed a couple beers.

"Kristen got to know [Stella] more when she was single again and really likes her," a source told Us Weekly.

Stewart and Maxwell first sparked dating rumors in December after they were spotted together in Savannah, Ga. The actress was filming a new movie about Lizzie Borden co-starring Chloe Sevigny.

"Kristen is dating Stella Maxwell," an insider told People at the time. "They are having fun."

"She spent several days together with Stella, who came to visit her," the source added. "She was with Kristen on the set most days and seemed to have fun."

Stewart previously dated singer Annie Clark, aka St. Vincent, former personal assistant Alicia Cargile, French singer SoKo and Twilight co-star Robert Pattinson. She said in the November issue of Elle that she's "not ashamed" of her fluid sexuality.
