Cardi B feels like she's ''losing her mind'' sometimes.

The 'Bodak Yellow' rapper - who has daughter Kulture with her husband Offset - admits it can be tough navigating fame and she has her down days too.

Responding to reports Selena Gomez has entered treatment for an ''emotional breakdown'', Cardi told E! News: ''When I met her, she was such a sweet, adorable person. She's really what you see. She's really a sweetheart. I just want to let her know, Girl, you're beautiful, you're rich and hold on because even sometimes I feel like I'm losing my mind. I just got to pray hard to God and get away from social media.''

Meanwhile, Cardi previously confessed she was ''a little bit happier'' before she was famous but is grateful she doesn't ''have to worry'' about her future anymore.

She said: ''My family, whatever they want, they get. Everything that I want to buy, I can get. I don't have to worry so much about my future ... Even though I'm happy, I feel like I was a little bit happier two or three years ago when I had less money. I had less people who had opinions about my life. I felt like my life was mine. Now I feel like I don't even own my life. I feel like the world owns me.''

And the 25-year-old rapper revealed she is working hard to make things better.

Speaking before she gave birth to Kulture, she said: ''This is my work ethic: I do not want to raise my future kids where I was raised, and I know the only way to do it is working, working, working, working, working. I don't want to live in a small Bronx apartment. I don't want to have three kids that got to share one room. I don't want my kids to go to school and get gang-affiliated. I don't want to do welfare. I don't.''
