Janet Jackson 'angry at Oprah Winfrey'

Janet Jackson is reportedly "furious" with Oprah Winfrey for interviewing her brother Michael's children on her chatshow.

Janet is said to believe that Winfrey used her family to increase the programme's ratings.

A source told the National Enquirer: "Janet is furious. She thinks Oprah took advantage of Michael's children for TV ratings. Janet told her Michael would be heartsick that Oprah used his kids as pawns.

"The two women had a blistering blow-up during a telephone call on the day that the show was taped. When Oprah made it clear that she was going ahead with the interview, Janet screamed, 'Oprah, you make me sick!'"

Janet is believed to be closer to Winfrey's friend Tyler Perry and is allegedly "threatening" to release secrets about the host.

The insider added: "Janet is closer to Tyler, and Oprah knows it. Now Janet is threatening to use that friendship to get back at Oprah.

"Janet has let Oprah know that Tyler has been very candid about sharing Oprah's secrets with her - and Oprah's definitely got secrets. Janet is so outraged that she's not above getting back at Oprah by spreading those secrets."
