Kristen Stewart has been leaning on her friends since splitting from Robert Pattinson. 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.

"Kristen is super sad. She's leaning on her friends," a source said.

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.
