Photo: Naked FKA Twigs showing off her 'engagement ring' in the bath

If you like to see musicians slipping and sliding around in a swanky bath then you're in luck, because a very naked FKA Twigs has appeared online, having a marvellous time and getting a bit pruney.

She spent her tuesday evening schmoozing at the Swarovski Crystal World reopening in Austria last night, and after a hard night of looking at sparkly things, she headed back to unwind in the tub. Which her stylist Karen Clarkson then posted a photo of on Instagram, obviously.

Because it's important to remember that if you have a bath and it doesn't go on social media, did the bath even really happen at all? Everything was kept covered up as much as poss with the help of some flexible knees and stylish arm posing, but one thing that WAS on show was that mysterious engagement/promise/nothing ring, rumoured to have been given to her by boyfriend Robert Pattinson. At least everyone thinks it's the ring. It could just be a shiny bit of wet skin, really.

It's been rumoured for a couple of months now that FKA Twigs and R-Pattz could be set to tie the knot, with T-Pain of all people seeming to confirm that they're engaged, and loads of speculation about them planning a 'casual wedding'.

That's all very lovely but to be honest we're actually more interested in the very uncomfy-looking strap lines all the way down her legs, which must have come from wearing THESE killer shoes all evening. Dedication.

What do you reckon to all of this then? Nakedness, swanky bath, potential engagement ring, flexible knees...... What is your comment on this?
