Another reality star has been recruited by CNN to host a prime-time talk show. Dr. Drew Pinsky has signed a deal for a new weeknight prime-time show on CNN’s sister channel HLN, which will launch next spring. HLN, formerly CNN Headline News, has a vacancy at 10 PM where it currently airs a rerun of Nancy Grace’s 8 p.m. show. Pinsky hosts Celebrity Rehab With Dr. Drew on VH1 and has also headlined other reality series dealing with addiction. Pinsky’s appointment follows CNN’s recent hire of America’s Got Talent judge Piers Morgan to succeed Larry King at 9 PM.
