Former 'American Idol' contestant Nikki McKibbin has been one of the success stories of 'Celebrity Rehab' (Sun., 9PM ET on VH1). So when Dr. Drew Pinsky and Bob Forrest saw her glazed eyes and slow speech in a video update, they were understandably concerned. Forrest made the trip to check in in McKibbin and see what's going on in her life.

It turns out that she's being medicated with addictive prescription meds like Lithium and Ativan, which was a huge concern for Forrest. McKibbin said she'd been very forthcoming about her past with addiction, so it was a surprise that her doctors were putting her on these particular drugs, though she said these were to wean her off of other drugs.

Some of you may have noticed that there was a little bit of a change in the Top 24 during the Wednesday episode of 'American Idol.' Chris Golightly, who originally auditioned in Los Angeles, made it to the Top 24, and was shown in a group shot toward the end of the episode, but when we had individual shots of the 24 semi-finalists at the very end, he was missing. So what's the story? Turns out, Golightly was less than honest with 'Idol' producers.

After nine seasons, viewers and contestants alike have (or should have) learned one thing: be upfront with 'Idol' producers. Season One contestant Nikki McKibbin was upfront about her stripper past, and was allowed to stay on the show. Frenchie Davis, however, failed to disclose that she posed topless on the web, and was ousted. Golightly's infraction was that he failed to tell producers that he had a record contract.

Welcome back to "AI Aftermath," where we explore Idol's past. Each installment, as one more American Idol hopeful is eliminated from the competition, we take a look back at contestants past who were eliminated at the same point. We'll examine how they did on the show and what they've been up to since their eliminations. In honor of Syesha Mercado's elimination this week, we'll be looking at other fourth place finishers.

This week: 3rd place finishers, featuring featuring Nikki McKibbin (Season One), Kimberly Locke (Season Two), Jasmine Trias (Season Three), Vonzell Solomon (Season Four), Elliott Yamin (Season Five) and Melinda Doolittle (Season Six).
