Their appearance at the high-profile party is a first for the pair.
The romance between Kristen Stewart and St Vincent has been declared ‘red-carpet official’ as the pair were seen out this week at the CFDA/Vogue Fashion Fund event in Los Angeles.
The A-list actress was first linked to the singer-songwriter back in August, after the pair attended a screening of Stewart’s new movie Certain Women.

St Vincent (real name Annie Clark) had previously been in a relationship with model Cara Delevingne. According to reports, the couple broke up in September, after a year-and-a-half together.
The newly in-love Kristen and St Vincent publicly debuted their relationship at the fashion show held at the Chateau Marmont in West Hollywood on Thursday.
Vogue reports the pair both looked super-stylish with Kristen cutting a chic figure in a black blazer and baggy Phillip Lim joggers and black loafers. St Vincent wore a cute cropped red and black houndstooth jacket with high-waisted black wide-leg trousers
The pair were seated next to one another in the front row beside A-listers Emma Stone and Katy Perry.
Kristen previously dated video producer Alicia Cargile and spoke openly about the relationship in the September issue of Elle UK, telling the magazine she was “really in love”.
“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 added. “Things have changed. And not just with me – we’re really allowed to encourage this new acceptance to develop and be awesome.”
The Café Society star also famously dated her Twilight co-star Robert Pattinson for four years. The pair split in April 2013.
