Kristen Stewart and Robert Pattinson's reunion rumors have been the toast of the month. However, there is no official confirmation whether ex-love birds will get back together or not. Fans hope that April 9 will not only be remembered as Stewart's birthday date but also the day when "Robsten" reunites forever. The buzz is that diehard "Twilight" fans will be trending "Robsten" reunion hashtag on Twitter all day tomorrow.

This is not the first time that "Robsten" reunification buzz has gone rampant on the web. Last year during Christmas and New Year's Eve, rumors were ripe that the couple would get back, but nothing of that sort happened. Both Kristen Stewart and Robert Pattinson celebrated the festivals with their respective families.

Moreover, at present Robert Pattinson is making to a lot of tabloids for his growing closeness to Katy Perry. It is being said that the two are more than friends. Perry has a solid support system in Pattinson and she thinks that he is the only guy who can help her sail through difficult situation.

"Rob has made Katy Perry promise to count on him for support, like she did for him when he split from Kristen Stewart. The question is, how far comforting will go - they always had this really flirtatious relationship," says a source to OK Magazine, as reported by the Entertainmentwise.

Since their break-up last year, Pattinson and Stewart have hooked up on numerous occasions but their relation did not go any further. They have been simply meeting as friends or the sake of their dogs Bernie and Bear. So it is highly unlikely that they will be reuniting for good this time.

Pattinson has already been linked to Dylan Penn in last few months and source say that Stewart has not done anything about it except waiting for Rob to come back to her.
