Giovanni Agnelli has stood up for Kristen Stewart

A close friend of Kristen Stewart has insisted that she didn’t get intimate with married director Rupert Sanders.

Kristen, 22, admitted last week that she’d cheated on boyfriend Robert Pattinson with the 41-year-old, but producer Giovanni Agnelli says their flirtation wasn’t sexual.

‘I’ll say right now what the manipulative media isn’t saying… Kristen Stewart did not have any type of sex with Rupert Sanders,’ Tweets Giovanni.

‘The spin that keeps growing on this story is staggering. There was NO on set affair. Stop printing LIES.’

In a statement released last week, Kristen said that her relationship with Rupert was a ‘momentary indiscretion’ and that her Twilight co-star Robert, 26, was the person she ‘loved and respected the most’.

But Rupert‘s brother-in-law Leopold Ross has claimed that their relationship went on for months.

‘It was from the last half of filming and all through post-production,’ Leopold tells The People, ‘clear into last week.’
