The 28-year-old singer got upset by some of the comments she'd received on her Twitter page, so the 'Chained to the Rhythm' hitmaker - who she was touring with - advised her to stay well clear of the remarks.
Bebe told news.com.au: ''I was at dinner when I was on tour with Katy Perry and went on my Twitter and was reading the comments and got really bummed about what somebody had said.
''She was like 'Why are you reading the comments? That's the number one rule, don't read the comments'.'
Meanwhile, the 'Meant to Be' singer recently spoke out about her ''everyday battle'' with anxiety, admitting she cries ''a lot'' and finds life ''tough''.
She said: ''I cry a lot. It's tough. I have my own therapist and I have people I talk to. It's an everyday battle, I feel.
''I don't wanna feed into it, but my lifestyle is so crazy. When I first went to my first year of college, I was so intense. I didn't know how to handle it and be around people.
''I was super anxious all the time. I was anxious when I was a little girl, I just didn't know what it was. Finally, when I figured it out, I was like, 'Oh. Finally, I understand. I have anxiety.'''
Bebe has always struggled with the idea of being ''accepted'', but that people have been able to relate to her the most when she has been going through a tough time with her ''fears and ''insecurities''.
She explained: ''I've always had fear and anxiety [about] wanting to be accepted.
''But when I've shined the most and people have related to me the most, was when I was able to not eliminate those anxieties, or those fears, or insecurities, but to kind of just push through them.
''Obviously, they always come back. They're never gone. But now I'm able to face them head on.''
