Reese Witherspoon's not happy with Robert Pattinson's decision

Robert Pattinson's pal Reese Witherspoon's fuming at his decision to forgive love cheat Kristen Stewart, 22.

Rob, 26, had sought refuge at Reese's ranch in Ojai, California, after his split from K-Stew in July.

But now he's giving her a second chance and Reese, 36, is furious.

'She sees Rob as a brother and wants him to move on. Infidelity rumours broke up her marriage to Ryan Phillippe - it's inexcusable for her,' says a pal.

'Reese is relieved she hasn't been asked to comment because her anger could boil over.

'She wouldn't have loaned Rob her ranch if she'd known he'd use it for the reunion.'
