Bobbi Kristina Brown has hinted she is planning a music career.

The 21-year-old daughter of late singer Whitney Houston claims to have inherited her mother's voice and teased fans she is preparing to put it to use. "Think about it.. She had 1babygirl, lungs and a GORGEOUS unforgettable voice .. Who do you think ONLY has HER vocal chords.. ? [sic]," she wrote on Twitter.

Bobbi - who's father is "My Prerogative" singer Bobby Brown - retweeted fans who gave her praise, and warned those who questioned whether she would be able to live up to her mother's high standards that she fully intends to. When user TayAmazin wrote, "@REALbkBrown lol girl. NOBODY has her vocals... But I wish you well! I'm excited to hear [sic]," Bobbi replied, "You underestimate what she MADE [sic]."

The young star is also rumored to be getting help with her career from Mariah Carey and former American Idol judge Randy Jackson.

"Mariah and Randy were close friends of Whitney's and were heartbroken after she died suddenly in 2012. They kept in touch. Now Randy has decided he wants to help Bobbi Kristina become a star - and Mariah told him she wanted in, too. Mariah would love to step in and provide mentoring to [Bobbi] because she and Randy have been so close... They have years of music experience between them and will share all their knowledge with Bobbi Kristina," a source said.
