|Kristen Stewart has surrounded herself with friends|
The 23-year-old actress and 'Bel Ami' actor are reportedly on a 'break' after calling time on their four-year romance, and Kristen has since surrounded herself with a support network of close friends to help her stay positive.
A source close to the star told HollywoodLife.com: "Kristen is super sad. She's leaning on her friends."
The brunette is said to have been spending a lot of time with her 'Twilight' co-star Taylor Lautner, who supported her when Robert was in Australia filming 'The Rover' earlier this year.
In the absence of his good pal, Taylor took Kristen out to see a concert and the pair enjoyed an athletic day out at the batting cages.
According to Us Weekly, Robert and Kristen have been "having problems" and "fighting a lot" recently, with things coming to a head on May 13, the day of the actor's 27th birthday.
Robert reportedly ditched the surprise party planned by Kristen for a guy's night out, leaving the actress in floods of tears.
This isn't the first time the Hollywood couple have called it quits.
Robert broke things off for two months last summer when Kristen was caught on camera kissing her married 'Snow White and the Huntsman' director Rupert Sanders.
They reconciled last autumn in time to promote the final 'Twilight' saga film, 'Breaking Dawn: Part 2' and appeared to have put their differences aside.
