The X Factor was all about big hair and even bigger results Wednesday night.
Carlos Guevara was the first Top 13 contestant to be eliminated as the show kicked off by announcing results after last week's technical glitch nullified the voting.
Then it was back to the '80s, as the contestants took on songs from the era of Madonna's fingerless-gloved heyday.
With a baby on the way, X Factor mentor Simon Cowell declared that he was quitting smoking, but in his own words: "I lied."
Claiming electronic cigarettes "don't work," the music mogul eagerly pulled out a pack of cigarettes to light up after taping an episode of his Fox singing competition on Thursday.
"There are a lot of boring things that happen when you have a baby," Cowell, 54, told reporters with a cheeky smile. "[You have to get rid of] sharp edges, cigarettes, alcohol … then there's [baby-proofing] the toilet. But I'll have a smoking room!"
One of The X Factor's contestants was supposed to be sent home Thursday after the Top 13 got down with Motown on Wednesday night.
But when voting information from Wednesday's show turned out to be incorrect – the result of a graphics error during the recap – contestants were asked to perform again on Thursday.
The impromptu performance show, which gave the singers less than 24 hours to prepare, was chaotic: Contestant after contestant was brought out in speedy fashion, and the judges were forced to deliver their comments quickly (often only one or two of the judges got a word in after a performance).
The craziness was summed up perfectly by host Mario Lopez, who said, "This is sort of like speed dating ... but speed singing."
The X Factor got down with Motown Wednesday night as the Top 12 performed hits from the legendary record label.
Make that the Top 13: The live show kicked off with a surprise, as Josh Levi, who was eliminated from the Boys team by mentor Paulina Rubio last week, was invited back as a wild card.
Levi, 15, sang "Who's Loving You" by the Jackson 5, and earned raves from the judges, including Simon Cowell who said, "You went from zero to hero."
At 54, X Factor contestant Lillie McCloud is enjoying a reality she thought had passed her by.
"I had pretty much given up on the idea of becoming a recording artist," McCloud tells PEOPLE. "I never thought I would be doing this again."
Before becoming one of season 3's top 12, McCloud enjoyed success in the 1980s and '90s under her birth name, Nicole, with international dance hits such as "Don't You Want My Love" and "Runnin' Away." But she had never enjoyed the artistic freedom she had hoped for.
After a baseball-induced hiatus, The X Factor returned with its own playoffs on Tuesday night, as one performer from each category – Boys, Girls, Over 25s and Groups – was eliminated.
Ellona Santiago, 17, kicked off the live show for the Girls with "Till the World Ends" by Britney Spears, which prompted a standing ovation from mentor Demi Lovato.
Bespectacled bookworm Danie Geimer, 15, sang "Wrecking Ball" by Miley Cyrus, a performance that had judge Simon Cowell asking, "How do we make you not boring?"
Sparks flew when Alex Kinsey and Sierra Deaton met on a beach back in 2009 – as he played Jason Mraz's "I'm Yours" on his guitar – and the sparks were there again when the duo took the stage during The X Factor's four-chair challenge on Thursday.
The Florida couple, who previously wowed the judges with their fun rendition of Britney Spears's "Toxic," delivered another memorable performance, taking on the Grease anthem "You're the One That I Want."
Romantic, sweet, original and pitch-perfect, the performance gave the judges chills.
"People are going to fall in love with you," Simon Cowell said, adding, "I like the fact that you put your own twist on the songs."
The X Factor's nail-biting elimination round got even more tense on Wednesday night when judge Paulina Rubio admitted she'd made a mistake and had second thoughts about a contestant she'd booted from the show.
With the Over 25s and Girls teams decided last week, Rubio's Boys were performing for their chance to make it to the live shows.
In a dramatic double-switch, Rubio initially sent home the painfully shy but vocally powerful Tim Olstad – who sang Miley Cyrus's "The Climb" – but then called him back, saying she'd been wrong, and had him take a seat in her final four chairs.
Paulina Rubio says there's "a lot of talent" on the current season of The X Factor. But in a competitive season like this one, what can contestants do to impress her and prove they have The X Factor?

Is there teen love in the air for pop star Austin Mahone and Fifth Harmony's Camila Cabelo?
"Austin caught Camila's eye when they were both in New York for the MTV VMAs [in August]," a friend of the teens tells PEOPLE. "They met the day before at the Arthur Ashe Kids Day and have been in touch ever since."
Back in December the "What About Love" crooner Tweeted his support for the 16-year-old brunette beauty whose group finished third on season two of The X Factor, "Hey gorgeous! Good job tonight. I voted for you."
Just a few months later it appears the two might be an item.
