Cymphonique Miller celebrates Nickelodeon's largest ever Worldwide Day of Play at the Ellipse on Sept. 24, 2011 in Washington, DC

*Another child of one-time rap mogul Percy “Master P” Miller is poised to bum rush Nickelodeon.

Cymphonique Miller, the sister of former Nick star Romeo Miller, debuts this Saturday at 8:30 p.m. in the new series “How to Rock” – a gig that would seem inevitable for a teen with two relatives in the spotlight. But the 15-year-old singer and actress says her career path was something she had to fight for.

“My dad actually didn’t even want me to be in the entertainment business because he just knows how crazy it can be, but I’ve just always loved it,” says Miller, “I’ve been singing since I was two years old. I started off in the church choir and I did my school community plays.”

She’s also performed on national school tours and in theme parks across the country, having tagged along with the likes of Raven-Symoné, Ashley Tisdale, Demi Lovato and JoJo. She made the finals in Radio Disney’s Next Big Thing contest.  Her songs, “Butterflies,” “Lil Miss Swaggar” and “Daddy I’m A Rockstar” made the rotation on Radio Disney.

“The music was just in me ever since I was a little kid, and it was just sort of a coincidence that I just happened to be in the Miller family,” she says.

“How to Rock,” based on the “How to Rock Braces and Glasses” book series by Meg Haston, stars Miller as Kacey Simon, a mean girl whose social standing takes a nasty hit when she is forced to wear braces and eye glasses.

She becomes the lead singer of the pop/hip-hop band Gravity 5, and the band’s success sparks a rivalry with The Perfs, a rival band featuring her mean girl archrivals.

Miller says the Gravity 5 songs will eventually land on a forthcoming “How to Rock” soundtrack. “We recorded many songs, but the type of music on the show is definitely not just limited to hip hop,” she explains.  “We have pop, rock, R&B, and hip hop, and we even do ballads.”

Cymphonique is no stranger to Nickelodeon fans. She is featured on Big Time Rush’s “I Know You Know” and sings the theme song for “Winx Club,” an Italian animated series on the network. When she was just beginning grade school, her dad was starring alongside her big brother on his own Nickelodeon show “Romeo!” which ran from 2003 to 2006.

Although Cymphonique has been surrounded on all sides by the entertainment business, she says her dad makes sure that her school books are always the number one priority.

“My dad’s all about education, and that’s what we put first,” she said. “So he’s, like, ‘Okay, even if you’re going to be in it, you’re still going to be going to school, and you still have to be making As.’ So, I have a tutor with me all the time everywhere I go.”

Just as important to Cymphonique as her studies is the ability to forge her own path in the entertainment industry without relying on her famous relatives to open doors. Below, she explains how she managed to audition for Nickelodeon without the network finding out who her father and brother were.
