Kristen Stewart "did not have sex" with director Rupert Sanders.
The 22-year-old actress admitted last week to cheating on boyfriend Robert Pattinson with the 'Snow White and the Huntsman' filmmaker but her 'Welcome to the Rileys' director Giovaani Agenlli insists their relationship wasn't sexual.
In a series of posts on twitter, he wrote: "I'll say right now what the manipulative media isn't saying ... Kristen Stewart did not have any type of sex with Rupert Sanders.
"the spin that keeps growing on this story is staggering. There was NO on set affair. Stop printing LIES (sic)"
He also hinted he knew her whereabouts following a "twitition" by her fans pledging their support to her following the affair.
He added: "Please don't ask how or where she is, or what she thought. Just know this: She saw the twitition, and the support video tonight. Thank you (sic)"
Kristen and Robert - who met on the set of 'Twilight' - are believed to have both moved out of the house they share together in Los Angeles following the affair, and he is thought to have stopped talking to her.
