The 'American Idol' judge is said to be worried the aspiring singer is
going down the same destructive path as her mother Whitney - who drowned
in a bathtub following a cocaine overdose in February - and told her
she needs to change her ways.
A source said: "Mariah decided it was time for some tough love. She told Krissy straight up that she knows she's not living right. It was a pretty harsh conversation and they both ended up in tears. But hopefully it had some sort of impact because Krissy needs to make some serious changes."
Bobbi, 19, has hit the headlines for the wrong reasons in the past few months and most recently smashed up her boyfriend's brand new car.
Bobbi accidentally struck Nick Gordon's Camaro with her own vehicle in the parking garage of their Georgia apartment complex, causing severe damage to the front of his sports car.
The accident came just weeks after Bobbi Kristina and Nick were involved in another crash that damaged his car.
The couple had been arguing at the time of the collision - which destroyed the entire front end of the vehicle - and Nick's Camaro was the only car involved. No one was injured.
