Looks like Kristen Stewart and St. Vincent are done playing coy about the nature of their relationship.

The 26-year-old actress and the 34-year-old singer held hands in New York City on Sunday after grabbing dinner together, openly showing PDA. Stewart dressed casually in a pair of black shorts and Vans sneakers, while the alt rocker also dressed down in a pair of Adidas sweat pants, a crop top, and a black blazer.

Stewart and St. Vincent (whose real name is Annie Clark) have been reportedly dating since Oct. 3, when the Twilight actress brought her to the New York Film Festival screening of her latest film, Certain Women, according to Us Weekly. "It's been very romantic," a source tells the magazine. "Kristen is always whispering closely in her ear and asking her opinion."

St. Vincent was last linked to 24-year-old supermodel Cara Delevingne, but the two reportedly split this past summer after dating for one year. In August, Delevingne gushed about their relationship.

"I'm completely in love," she told British Vogue. "Before, I didn't know what love was -- real love. I didn't understand the depth of it. I always used to think it was you against the world. Now, I know the meaning of life is love -- whether that's for yourself or for the world or your partner."

Stewart and St. Vincent's reported relationship is also surprising given Stewart's recent openness about her love for her on-again, off-again girlfriend, producer Alicia Cargile.

"Right now I'm just really in love with my girlfriend," she told Elle UK bluntly in July when asked about Cargile. "We've broken up a couple of times and gotten back together, and this time I was like, 'Finally, I can feel again.'"

"I'm not ashamed and I'm not confused," she also told Elleearlier this month about her love life.

It appears Delevingne has been leaning on her famous gal-pals for support. Last Thursday, the Suicide Squad actress stepped out with Taylor Swift, Dakota Johnson, Serena Williams, and Karlie Kloss in NYC, when the squad attended a concert by Sting's daughter, Eliot Sumner, at the Bowery Ballroom.
