The Truth About Robert Pattinson's 'New Girlfriend'

Robert Pattinson's new 'mystery brunette' has been revealed... and it's not what you think (phew)

Robert Pattinson's new 'mystery brunette' has been revealed to be his trainer, who is helping the actor bulk up for his new role in Mission: Blacklist.

E! News reports that the gorgeous brunette who's been spotted leaving the gym with Rob on more than one occasion is helping the actor follow the strict fitness regimen he needs for his new role, where he'll be playing a young military interrogator who helps lead the mission to capture Saddam Hussein.

The gym bunny fitness pro was snapped smiling from ear to ear as she left the gym after a workout session with Robert, wearing a turquoise workout vest, black leggings and black sunglasses.

According to E! News, she's the Twilight star's go-to trainer when his primary PT, Harley Pasternak, is unavailable.

The hunky actor recently told Harpers Bazaar Arabia that he's been missing out on roles because of his less-defined physique (we don't believe it!):

'I think I don't get some jobs because I don't go to the gym. I am literally the only actor in LA who doesn't have a six pack. Although I am going to have to change that. In my next film I have like three intimate scenes so I am literally thinking of those to get in shape.'

So, does this mean Rob's still single? And buffer than ever before? We're starting to feel a little dizzy.
