Singer Kelly Rowland has aired her true feelings about pal and former Destiny's Child bandmate Beyonce and a past abusive relationship in a revealing track on her new album.

In the lyrics of Dirty Laundry, Rowland admits she was jealous of Beyonce as her solo career took off while she was battling personal problems at home with an unnamed slap-happy lover.

The former Destiny's Child star sings, "When my sister was on stage killin' it like a motherf**ker/I was enraged, feelin' it like a mother f**ker/Bird in a cage/You would never know what I was dealin' with/Went our separate ways but I was happy she was killin' it."

She adds, "Bittersweet she was up, I was down/No lie, I feel good for her but what do I do now?/Forget the records, off the record, I was going through some bulls**t/Post-Survivor, she on fire/Who wanna hear my bulls**t?"

Rowland goes on to detail her past abusive relationship, revealing, "Meanwhile, this n**ga is putting his hands on me/You don't know the half of this industry/When you're soaked in tears for years, it never airs out/When you make pain look this good, it never wears out."

She also claims Beyonce told her to leave her ex-lover after he left her "battered", but adds, "I'm on the kitchen floor, he took the keys".

The singer also reveals that her abusive former boyfriend tried to turn her against her family and friends by insisting that he was the only person who truly loved her, but it seems all is well between Rowland and Beyonce again - as was apparent onstage at the Super Bowl Half-Time Show in February (13), when Destiny's Child briefly reunited. Rowland sings, "I missed ya" to Beyonce.

Rowland has admitted that recording Dirty Laundry was an emotional experience, stating, "It took me days to record. I had to get past being so upset and actually sing the song, not sob through it."
