Melbourne, August 10 (ANI): Robert Pattinson, who has been left devastated after girlfriend Kristen Stewart cheated on him, has now turned to his ex-girlfriend Nina Schubert for some comfort and advice.

Schubert, who is proving to be his rock, has apparently warned him not to make any hasty decisions when it comes to his love life.

The pair dated when the actor was growing up in London and still share a close bond despite their split.

Rob and Nina grew up together... She was Rob's first serious girlfriend. It only didn't work out between them because he had to move to LA for work. She's been there for him more than anyone else these past few weeks, the Herald Sun quoted a source as telling Look.

Nina's told him he shouldn't make any hasty decisions now and he should take all the time he needs.

Robert has been phoning Schubert and they have been discussing his relationship with Stewart.

He calls her upset, at 2am, saying over and over how stupid he feels for not realizing what was going on between Kristen and Rupert, the source revealed.

She's there to listen, the source added. (ANI)
