According to Look Magazine, the ‘Cosmopolis’ star is working on a six-month image overhaul.
His desire for change stems from the revelation that his longterm girlfriend Kristen Stewart had an affair with married “Snow White and the Huntsman” director Rupert Sanders.
"Rob wants to show Kristen what she's thrown away," an insider revealed to Look magazine.
"He's spent a fortune in the past two weeks on his hair, teeth whitening and a spray tan. He's bought an array of Gucci suits, which cost £2,000 a pop and he's stepping up his exercise regime with trainer Tamsyn Hamilton to get in shape."
In the wake of his split from Stewart, the 26-year-old has reportedly spent time with fellow Hollywood star Leonardo DiCaprio recently.
"Leo has been one of Rob's role models for years, and Rob was totally taken by surprise when Leo called him. He invited Rob along on a getaway he's planning when he's in Puerto Rico for the wrap party on the movie he's producing, Runner, Runner," a source previously revealed.
