Whitney Houston's sister-in-law has hit back at criticism she sold photos of the singer's 'drug den' to a US tabloid to make money, insisting she did it to help the fallen pop star. Bobby Brown's sister TINA exposed the extent of Houston's drug problems with a tell-all article in the National Enquirer last year (05) after warning the singer she would go public with her junkie hell if she didn't clean up. Brown insists she didn't speak to the tabloid and hand over photos she took of Houston's squalid drugs den out of malice or to make money - it was all about love. Speaking to urban publication Sister 2 Sister, the former model explains she had to do something drastic because she feared Houston would wind up dead if she didn't give up drugs. Brown says, "Every time I got called (by Houston) I was scared I was gonna walk in there and she was gonna be dead. "I told her, 'The next time I come in here... and the situation is the same, I'm snapping pictures and I'm gonna do what I gotta do. Maybe if you see yourself in black and white... Maybe you need a jarring experience to wake you up out of this.' "I had several motives behind what I did. One was because I loved her and I was tired of seeing her like that." Houston's sister-in-law admits the singer's drug use got so bad last summer (05) it prompted her to get sober after years of substance abuse, and her tabloid tell-all has brought her and the pop star closer together than ever. Brown adds, "She called me and she was like, 'You did it...' We started talking and she started crying and was like, 'Why did you do it?' "I was like, 'Nip (Houston's nickname), it's gonna help you, man. When you see it, read it. Read what you do.'" Brown uses the interview with Sister 2 Sister publisher JAMIE FOSTER BROWN to dismiss reports she was paid $200,000 (GBP112,000) for taking her story to the Enquirer: "I'm broke now, so it couldn't have been that much money."
