Also: John Quiqones' Interview with Lindsay Lohan's Headline-Making Father

Plus: Chris Cuomo Investigates Sanitary Conditions on Cruise Ships

In an exclusive "Primetime Live" interview with Diane Sawyer, supermodel Naomi Campbell speaks candidly about her tempestuous life on and off the runway. Campbell has reached the pinnacle of the modeling world, gracing the covers of countless magazines. Yet this famous face has become almost equally famous for what critics call a sometimes surly demeanor. She addresses the persistent rumors of a temper that has allegedly led her to lash out violently at others, saying the tabloid stories are simply untrue. Campbell also reveals to Sawyer how drug addiction took over her life - and how she got it back. "Primetime Live" airs THURSDAY, FEBRUARY 24 (10:00-11:00 p.m., ET) on the ABC Television Network.

Also: Actress Lindsay Lohan's father, Michael, has turned his family's private difficulties into a very public spectacle. His bitter divorce battle with wife Dina and several run-ins with the law have made headlines for months and created major embarrassment for his estranged daughter. Just days ago he was involved in a fiery car accident and was charged with driving while intoxicated. In an interview with John Quiqones, Lohan explains exactly what he wants from his family - he's asking for half of Dina's profits from managing Lindsay's career, but reportedly thinks the family can earn millions more by starring together in a television reality series. Quiqones also asks Lohan whether he worries about the impact all this off-screen drama could have on his daughter's burgeoning career.

Plus: A "Primetime Live" investigation takes a closer look at just how clean your cruise ship cabin might really be. Chris Cuomo reports the findings of dozens of swab samples taken from cabins and public places on four different cruise ships.
