Kristen and Annie finally seem to have confirmed their relationship by showing up together at a fashion event in Hollywood. It seems the couple first got close when Kristen invited St. Vincent to a screening of her newest movie 'Certain Women' at the New York Film Festival on October 3rd. A source told People that 'they have spent almost every day together' since then.

It marks Kristen's third relationship with a woman this year; she dated French singer Stephanie 'Soko' Sokolinski in March and then her former assistant Alicia Cargile in July. Annie Clark, meanwhile, split ended her year and a half relationship with 'Suicide Squad' star Cara Delevingne in September. 

Kristen Stewart's love life has been a headline-grabbing subject since she was snapped kissing the director of 'Snow White and the Huntsman', Rupert Sanders, while in a long-term relationship with her 'Twilight' co-star Robert Pattinson. She only opened up about her fluid sexuality this year, refusing to label herself as bisexual or otherwise.

'I had to have some answer about who I was', she told Variety in an interview. 'I felt this weird responsibility, because I didn't want to seem fearful. But nothing seemed appropriate. So I was like, 'f***, how do I define that? I'm not going to'. Plus, I didn't want to f*** with other people.'

She re-iterated her stance on her sexuality earlier this month in an interview with Elle, where she insisted that she was 'not confused' and dating a guy to her 'wasn't real life anymore'.
