R. Kelly is preparing to sue Lifetime for airing their Surviving R. Kelly docuseries.

According to a TMZ report published earlier today (Jan. 3), the "I Admit" singer's lawyer sent a letter to the network warning them that the six-part program is "packed with lies." The letter also states that if Lifetime proceeds to air the special as intended tonight, then Kelly will file a federal lawsuit on the same day.

After the premiere of the series in New York City was interrupted by a bomb threat, Lifetime plans to deliver the first installment of the six-hour program as part of a three-night event. Surviving R. Kelly features a slew of women who shed light on the abuse the veteran R&B singer allegedly subjected them to. R. Kelly's ex-wife Andrea Kelly, Jerhonda Pace, Kitti Jones, Asante McGee, Lisa Van Allen and singer Sparkle all appear in the docuseries.

Surviving R. Kelly is said to explore new allegations of sexual, mental and physical abuse that Kelly inflicted upon women and unearth never-before-heard stories from his past relationships with singers like Aaliyah. In a new preview of the upcoming docuseries, a former background singer of R. Kelly’s Claims to have seen a then-27-year-old Kelly engage in sex with a then-15-year-old Aaliyah.

However, Kelly's lawyer not only refutes all the allegations but he also claims that the singer possesses two, five-minute audio recordings that reportedly proves Lifetime knows "some of the girls are lying, but that the budget was too high to turn back now."

Lifetime's Surviving R. Kelly is set to debut tonight at 8 P.M. EST.
