The pair had an evening hopping around the capital's trendiest hotspots; they had previously been at the launch of #NoArtistsNoArt at Lights of Soho to support the campaign to raise awareness of independent venues in Soho having to close down due to rent and rate hikes. 

Kristen was dressed casually for the romantic night out in a pair of grungy ripped black jeans and a simple grey T-shirt.

She kept incognito with a black beanie pulled low over her face, and added a trendy silver chain to the look.

Stella, who has walked in the famous Annual Victoria's Secret Fashion Show, too went for a low-key look with an unusual lace midi skirt with a pair of black Converse trainers that laced up past her ankles.

Seemingly carrying both she and her girlfriend's belongings, she slung two large holdalls over both of her shoulders, and swept her golden tresses back off her face in a ponytail.

Kristen previously dated her Twilight co-star Robert Pattinson after meeting him on the set of the movie franchise in 2009.

They split after she was pictured kissing her Snow White And The Huntsman director, Rupert Sanders, emerged in July 2012. 

Kristen and Stella are said to be on the brink on moving in together, with sources saying the blonde beauty 'spends all her time' at her girlfriend's house.

Us Weekly quoted a source last month who'd alleged that Kristen and Stella 'have moved in together' and that Stella 'spends all her time' at her flame's Los Feliz home - this despite the fact Stella purportedly hasn't given up her own Big Apple digs.

Kristen brought up her sexuality during her Saturday Night Light hosting gig in February, trumpeting to Donald Trump in her monologue that she's 'so gay, dude.'

In an interview The Guardian ran in March, Kristen said: 'You’re not confused if you’re bisexual. It’s not confusing at all. For me, it’s quite the opposite.'

She'd previously held forth on the subject at greater length in that interview, saying: 'The whole issue of sexuality is so grey. I’m just trying to acknowledge that fluidity, that greyness,' she noted, noting it's 'always existed' and theorizing that 'maybe only now are we allowed to start talking about it.

Of society's evolving attitude to LGBT issues, the actress had said: 'Oh, I think things are changing.

'I mean, I don’t think I would have approached my life differently if that hadn’t been the case. But who knows?'
