Is Kristen Stewart cheating on girlfriend Stella Maxwell with her ex Alicia Cargile?

Even though Kristen Stewart and Stella Maxwell appear inseparable when they are spotted on romantic date nights and exotic trips, the couple is no stranger to whirlwind cheating rumours. Most recently, a US tabloid claimed that the Twilight actress has been cheating on her model girlfriend of seven months.

Not only did the sensational report accuse Stewart of indulging in a secret affair but also alleged that she has been seeing her ex Alicia Cargile behind Maxwell's back.

Apparently the 27-year-old actress – who has dated both men and women in the past – was "caught double-dipping with her lady loves," as per National Enquirer.

Elaborating further on the alleged affair, the tabloid claimed that "just weeks after setting up house with Victoria's Secret model Stella Maxwell, the Twilight vamp was caught sneaking around with ex-gal pal Alicia."

A source claimed that Stewart was spotted at Cargile's home recently and "looked like something was going on."

The latest rumour comes amid talk of Stewart and Maxwell moving in together into the actress' LA apartment.

However, popular gossip debunking site Gossip Cop has squashed the fabricated report as a false claim, saying there's "no truth" to the tabloid's whirlwind speculations.

The website further asserts that Stewart and Maxwell are going strong, despite the Personal Shopper actress' friendly relations with her ex Cargile.

"[The model] and Kirsten have a good thing... They're two peas in a pod," a source told Gossip Cop. And clearly that seems like the reality as the couple continues to trot the world together, with the latest sighting in Paris.

While in the city of love, Stewart and Maxwell – who are said to be in town for the Paris Haute Couture Fashion Week – were spotted stepping out for some private time. Although, it's not known if the Victoria's Secret Angel is walking at the shows, her girlfriend of seven months seems happy to accompany her.
