FKA Twigs raised eyebrows when she arrived with her other half Robert Pattinson at the Met Gala in New York, showing off what appeared to be an engagement ring and an erotic dress.

The singer and the former Twilight actor – who are thought to have become engaged after just six months of dating – made their red carpet debut as a couple at the event.

The Ivor Novello-nominated musician, real name Tahliah Debrett Barnett, wore a brightly coloured Christopher Kane dress, which was printed with naked bodies and even featured male genitalia.

She also appeared to be wearing a large engagement ring, confirming rumours that the British stars are set to wed.

FKA Twigs has previously said of dating the world-famous actor, whom she met after the end of his romance with actress Kristen Stewart: “The positivity that I get from (my relationship) makes the more challenging aspects… very worth it.”
