Robert Pattinson's fiance poses in bathtub wearing 'only' her ring

Singer FKA twigs attended the Swarovski Crystal World reopening evening gala in Wattens, Austria, on Tuesday night and the singer decided to unwind after the soiree with a nice bubble bath.

The 27-year-old singer posed naked in the bathtub with nothing but her engagement ring.

"Always have a bath before bed," her stylist Karen Clarkson posted the sultry shot on her Instagram.

FKA twigs (real name Tahliah Barnett) strategically covered her modesty.

With her hair in a messy ponytail on top of her head, FKA strikes a pose for the camera and gives a small smile.

Earlier in the night, the singer showed off her new bling, displaying the sparkler on ring finger. 

She wore an opalescent dress, pulling together all of her eclectic tastes with flamenco sleeves and gothic boots.

News broke earlier this month that the Twilight actor, 28, and FKA twigs, 27, were set to tie the knot although they have stayed mum on the reports.

However, we just got a glimpse of the diamond serpentine-like piece of jewelry.

She wore a ring on that finger during an outing in Venice, California, and again on the red carpet in Austria.

FKA will take the stage for the Red Bull Music Academy Festival at the Brooklyn Hangar on May 17, 18 and 19.
