“He`s really insecure about his shirt being off,” contactmusic.com quoted a source as saying. He is believed to have taken up paddle-boarding sport after being urged by girlfriend Kristen Stewart to lose a few pounds.
“Robert`s put on nearly 10 lbs eating cheeseburgers and drinking beer while he`s not been working. 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,” the source added.
