The pair, who was seen flirting and posing for pictures together last year, fell victim to a string of controversial headlines from Rihanna and her reconciliation with Chris Brown and have parted ways since then, the Mirror reported.
Meanwhile the 28-year-old Perry was seen hugging her two new buddies Selena Gomez and Kristen Stewart at the Nickelodean''s Kids'' Choice Awards.
A source told US magazine last month that the girls aren''t tight anymore because Perry doesn''t approve of Rihanna dating Chris Brown, after he brutally attacked her.
