Kristen Stewart is back in the dating pool and has reportedly started seeing alt rocker St. Vincent.

Us Weekly is reporting that the former "Twilight" star and her new love interest have been together for just a few weeks. Kristen brought the rocker to the New York Film Festival screening of her latest film, "Certain Women," on October 3.

"They spent almost every day together after that," Us' source said.

Kristen and St. Vincent, who previously dated Cara Delevingne, were first seen together in late August at a comedy show in Los Angeles. On Oct. 4, they were spotted at lunch in New York and photographed the next day walking the streets of the Big Apple together. Us reports that Kristen also attended St. Vincent's concert in Los Angeles on Oct. 9.

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

Previously, Kristen dated video producer Alicia Cargile, but they haven't been seen together since August 27.

"Right now, I'm just really in love with my girlfriend," the actress said of then-girlfriend Alicia in Elle U.K.'s September issue. "We've broken up a couple of times and gotten back together, and this time I was like, 'Finally, I can feel again.'"

Kristen previously dated her "Twilight" co-star Robert Pattinson. Normally tight-lipped about her private life, she told the mag that she is more open with her personal life since she began dating women.

"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," she said. "It opened my life up and I'm so much happier."

In Elle's November issue, she again spoke a bit about her love life and her decision to be a little more transparent.

"Things have changed," she said. "And not just with me — we're really allowed to encourage this new acceptance and be awesome."
