Kristen Stewart dating St. Vincent - report

Actress Kristen Stewart has reportedly embarked on a new romance with Cara Delevingne's ex-girlfriend St. Vincent.

The Twilight star was said to have first stepped out with St. Vincent at a comedy show in Los Angeles in late August (16), while Kristen allegedly took the rocker as her date to the New York Film Festival last week (ends07Oct16) to attend a screening of her new movie, Certain Women.

"They spent almost every day together after that," a source tells Us Weekly magazine.

They are said to have enjoyed a series of dates in the Big Apple before returning to California, where Kristen was spotted in the audience for the singer's Los Angeles concert on Sunday (09Oct16).

"It's been very romantic," the insider adds. "Kristen is always whispering closely in her ear and asking her opinion."

The actress, 26, and 34-year-old St. Vincent have yet to comment on the romance rumors.

Kristen, who previously dated her Twilight co-star Robert Pattinson, was most recently been linked to French singer Soko and her former assistant Alicia Cargile, who she was last pictured with in August (16).

St. Vincent, real name Annie Clark, split from model/actress Delevingne over the summer (16) after more than a year together.

The relationship news comes just days after Kristen opened up about her love life in a candid interview with Elle magazine for its Women in Hollywood issue, insisting she isn't "ashamed" or "confused" about her sexuality.

"Things have changed. And not just with me - we're really allowed to encourage this new acceptance and be awesome," she said of changing attitudes across the world.

Kristen had previously touched on her romance with Alicia in a chat with Elle U.K. earlier this year (16), when she admitted their romance wasn't perfect.

"I think also right now I'm just really in love with my girlfriend," she said at the time. "We've broken up a couple of times and gotten back together, and this time I was like, 'Finally, I can feel again.'"
