Aaliyah: The Princess of R&B (8 p.m., Lifetime) - The unauthorized biopic based on the life and tragic death of Detroit-raised singer Aaliyah may not win any awards (early reviews have not been glowing) but it’s still a must-see for fans. The movie tracks the young star’s hard work and determination to succeed, from her appearance on “Star Search” at age 10 to her death at at 22 in a plane crash – but apparently glosses over her controversial marriage (at the age of 15) to singer R. Kelly. And despite that brief lapse in judgement (the marriage was annulled), producer Debra Martin Chase describes the film as inspirational. Alexandra Shipp plays Aaliyah, Cle Bennett plays R. Kelly and Anthony Grant plays Damon Dash.
