On The Rocks? Kristen & Stella 'Barely' Spoke To Each Other During Coachella Bash

Kristen Stewart and girlfriend Stella Maxwell appeared to be on the rocks while celebrating Coachella this weekend. A source exclusively told RadarOnline.com that on Friday, April 13, the actress and the Victoria's Secret model arrived at a private bash hosted by Poppy LA at an estate in Palm Springs — but they barely spoke to each other!  Click through to see the awkward photos and learn more.

"Kristen and Stella did not look like a couple at all, they weren't holding hands or kissing like they usually would, and barely said three words to each other all night," an eyewitness told RadarOnline.com.

To make matters worse, model Bella Hadid — who allegedly kissed Maxwell backstage at a fashion party in London last earlier this year — turned up to join the party!

Meanwhile, Stewart, 28, and Maxwell, 27, remained at the bash hosted by Kourtney Kardashian and Kylie Jenner. They were surrounded by A-lister pals like Post Malone and Diplo, but they rarely spent any time together!

As RadarOnline.com readers know, this is not the first time Stewart and Maxwell have seemed at odds. The two have battled relationship issues from the very start, with the Twilight star constantly getting jealous of her girlfriend's flirty ways and model gal pals.

Before dating — and allegedly moving in with — Stewart, Maxwell was also linked to Miley Cyrus, Taylor Hill, Lily Rose Depp and Barbara Palvin, among others.

Stewart has been linked to ex Alicia Cargile and Stephanie "Soko" Sokolinksi, as well as former fiancée Robert Pattinson and film director Rupert Sanders.

Continued the eyewitness to RadarOnline.com: "Later on in the night Kristin was rolling her eyes at Stella, and it seemed they were on the rocks or had had a row before the party."
