A diva like Whitney Houston always get her way, but not when it comes to working with R. Kelly.

The legendary superstar and Pied Piper of R&B collaborated on two songs for her new album I Look to You, including the title track and “Salute.”

“My dear, dear R. Kelly,” Whitney said at a listening for her album in Beverly Hills on Thursday. “Some people just have their own world and R. Kelly, he has his own world.”

She said working with the “Ignition” singer was somewhat of a challenge. “You have to step into his world and I kinda stepped in and stepped out for a minute,” she laughed. “That’s a story we’ll keep between him and I—forever.”

Whitney didn’t leave without acknowledging Kellz’ contributions to her album and the music industry. “[There] would not have been a ‘Salute’ or ‘I Look to You’ without Robert Kelly, who is by far one of the best singer-songwriters in the industry today.”
