Kristen Stewart shares steamy kiss with new girlfriend Sara Dinkin

She ended things with her ex Stella Maxwell just one month ago.

Kristen Stewart was snapped sharing a steamy kiss with her new girlfriend while on a drive Thursday night in Los Angeles.

The 28-year-old and her lady love, Sara Dinkin, were on their way to take a workout class together when they stole a quick smooch.

The pair were headed to a Brazilian Jiu Jitsu class in Hollywood when they were seen stopped at a traffic light.

Before the red light could turn green, the Twilight star leaned over to her passenger for a brief lip locking session.

The new lovebirds seemed to spend the entire day together as they were spotted earlier walking their dogs.

On both outings, Kristen sported a white sweatshirt along with white Adidas Swisstex Direct sweatpants and a baseball hat.

Sara also donned a white sweatshirt along with black Adidas sweatpants. Dinkin has worked as Kristen's stylist hence the similar fashion sense.

The Panic Room star broke up with her supermodel girlfriend Stella Maxwell in December after being together since 2016.

Maxwell is reportedly furious that Kristen has gone public with her new relationship.

'They made a pact not to rub it in each other's faces by dating anyone else publicly for a while,' an insider told RadarOnline.

Adding: 'Kristen couldn't help herself and decided to go public with Sarah almost straight away,' the source said.

In the past week, Stewart has been spotted out with Dinkin several times.

Radar reported that Stella has 'been knocked sideways at how brutal Kristen's been.'

'The worst part is that they share a lot of mutual friends,' the revealed, 'all of whom are having to take sides because the girls won't speak to each other at all now.'

Kristen previously dated her Twilight franchise co-star Robert Pattinson, 32, from 2009 to 2013.

The pair took a break in 2012 when she had an affair with her Snow White And The Huntsman director Rupert Sanders, 47.

She dated her assistant Alicia Cargile on and off in 2015 before a brief relationship with French singer Soko, 33.

Kristen then romanced singer St. Vincent, 36, in 2016 for a few months before moving on to a relationship with Stella. (Daily Mail)
