A source tells Hollywoodlife.com,
“Katy’s friends are doing everything they can to help keep her happy and just be there to listen to her. Rihanna has been unbelievable and checks up on her every day and even invited her on a trip. Katy even asked Rihanna to meet her in Vegas and be there with her. Katy has really lost her appetite though. She is doing her best to remain upbeat while at work but she is deeply hurt.”
