A source close to the 'On The Road' star told HollywoodLife.com: "She is still in love with Rob. As far as her wanting to date anyone else, the answer is 100 percent absolutely not."
The insider explained that the brunette beauty, who met the actor on the set of the 'Twilight Saga', "misses her best friend. It's like a part of her has died and she is still going through the grieving process."
The insider added: "Kristen has been just laying low, hanging out with her closest friends and trying to stay out of the spotlight as much as possible."
But the actress is preparing to throw herself back into her work in a bid to get over their split, and recently landed roles in both 'Camp X-Ray' and 'Sils Maria'.
She has a busy summer ahead after committing to shoot Peter Sattler's politically charged flick and Olivier Assayas' new drama back-to-back.
