London, Apr 1 : Singers Katy Perry and Rihanna have formed a special bond, and become inseparable in recent weeks.

Perry, 24, gotten in touch with 21-year-old Rihanna to offer her help after news of her allegedly being assaulted by Chris Brown broke out in February.

The ‘I Kissed a Girl’ singer has been helping Rihanna get over the ordeal, and has also played a key role in cheering her up by taking her for girlie nights out.

“Katy was there when Rihanna needed her the most and as terrible as the stuff with Chris is, at least one good thing has come of it,” the Sun quoted a source as saying.

“Both of them have had man troubles recently so they are enjoying having some girlie time,” the source added.

The two are even hoping to find time in their busy schedules to go for a luxury girlie getaway to Puerto Rico. (ANI)
