Since this was before his High School Musical days, he introduced himself as the star of Summerland.

She lost to 12-year-old Marty Thomas, who was sure Britney was going to beat him.

She told Esquire, "I would put that in the category of things I was doing while I was auditioning to try to make ends meet. I went from working in the US Embassy in Argentina to ending up on Deal... It helped me to understand what I would rather be doing."  

She told the Observer, "I thought it was important for the audience for that show to see a Black rapper and media mogul embracing a trans woman of color on television.  I was hoping it might change things for me and other trans women of color on the streets and in Black communities. I never really wanted to be a personal assistant. I have always wanted to be an actor."

The MTV series sought to re-create the success of the '80s boy band Menudo, which originally brought stars like Ricky Martin and Robi Draco Rosa into the spotlight.

The group recorded one album together before disbanding in 2005.

She performed a series of impressions. 

The cast members helped her remedy a wardrobe malfunction.

She was awarded the part of Laurie, but only one episode of the reboot ever aired.

She joined the cast in 2015 and stayed on for two seasons. 

They're known for movies such as Crazy, Stupid, Love and Warm Bodies.

She later returned to the show as a judge. 

She was only 19 at the time. 

She left in 2016 as her rap career was taking off. 

At 17, she became the youngest winner in Idol history.

He teamed up with fellow YouTuber Meghan Camarena.

Five years later, she hit the top of the charts with "Call Me Maybe."

She didn't win, but she went on to record her first hit five years later. 

He came in second on his episode.

She was part of Eden's Crush, which was comprised of Popstars winners, before joining the Pussycat Dolls.

She told Yahoo! Music, "It was a great platform to get myself kind of accustomed to being in the industry and seeing what it was like being away from my tiny little hometown in Texas."
