Kristen Stewart puts Robert Pattinson on diet

London, Apr 10 (ANI): Kristen Stewart is making her boyfriend Robert Pattinson go on a diet.

The 22-year-old actress is hoping to get him back in shape before fans start pointing it out.

"Robert Pattinson's put on nearly 10lbs eating cheeseburgers and drinking beer while he's not been working," the Daily Star quoted her as saying.

"Kristen's told him to pull himself together. He hates the gym, so she's encouraged him to take up paddle surfing to try and work off the excess calories," she said.

But despite Stewart's less than friendly slimming advice for her 'Twilight' boyfriend still went all out for her 22nd birthday.

The 25-year-old hunk made a huge effort to buy Stewart her own film-making gear.

"Robert has been searching shops in Hollywood for movie equipment," a source said.

"Kristen's always dreamed of being behind the camera. He also organised a big banquet," the source added. (ANI)
