Howard read a list of candidates to replace his 'America's Got Talent' co-judge, Sharon Osbourne, but swore TMZ had some bad information. Still, Howard weighed in on each: Shannen Doherty: "From 'Beverly Hills 90210'? … She's nutty, right? Can she be on time?" Leann Rimes: "Sounds like they might have to put her in a straightjacket, but that's kind of interesting. ... 'Weren't you in rehab for Twitter?' That's what I'd say if she ever gets out of line." Carly Simon: "I think Carly Simon would be cool. I'm talking about terms in being on time. … [And] Carly could be a crier. Or could be trained to be one."
