Los Angeles, Oct 28 (IANS): Actress Kristen Stewart and musician St. Vincent made their public debut as a couple on Thursday, walking the line at the CFDA/Vogue Fashion Fund Show at the Chateau Marmont here.

The duo posed together in black shades, reports people.com.

While Stewart was wearing a tailored black blazer and cuffed tweed pants with a tuxedo stripe detail, St. Vincent showed off her midriff in a cropped long-sleeve plaid top and chic black plants.

Others present at the venue were actress Emma Stone, and singers Katy Perry and Ciara.

The event featured collections from ten emerging designers of all kinds from across the country -- each competing for the top prize of $400,000, which will be announced next month.

While this was the first time the new couple have hit the carpet together, they have been nearly inseparable since Stewart invited St. Vincent to the New York Film Festival screening of her new movie, "Certain Women", on October 3.

Stewart recently broke up with Alicia Cargile, while St. Vincent was dating actress Cara Delevingne until they split earlier this year.
