Cymphonique makes 16 extra sweet.
Cambio was invited to the How to Rock star's Sweet 16, complete with go-go dancers, Pinkberry, glitter tattoos and an awesome photo booth!
"I am so exited today," said the guest of honor. "When the day came, I thought there would be so much pressure, but it's actually really calm."
One of the most important parts of any Sweet 16 is the perfect outfit. Cymphonique shined in a yellow, sequin-accented Versace gown and matching shoes.
"I actually did this thing on twitter where I had my fans help me decide what I should wear," she said. "I decided yellow because I love gold, gold is my favorite color."
Romeo Miller, who also got his start on Nickelodeon, said he is very proud of his sister. "This is a day that comes once, and I think especially for girls, this is like a fairytale day."
"It's like déjà vu, you know? I had the No. 1 show on Nickelodeon, and now she does. The good thing about that is that I can give her a lot of tips and pointers," said Romeo. "Whenever she has a problem or wants to know anything, I'm able to help her out on it."
Romeo (giving Cymphonique a hug, below, with their dad, rapper Master P), being a protective older brother, also told us that he would keep a close eye on his sister at the party.
"I just want her to have fun. If any boys come too close though, I will pop up from behind," he said with a laugh. "I'm on security duty."
We asked Cymphonique's guests to share their personal favorite birthday memories.
"It was a snatch breakfast birthday party. You wake up and actually go surprise all your friends and wake them up in bed and you take them to breakfast," said Cymphonique's How to Rock costar Halston Sage.
"For my Sweet 16, my present was singing the national anthem at a Lakers game," said fellow Nickelodeon star Ashley Argota, "It was one of my biggest dreams come true."
"One of my favorite things I used to do when I was younger is instead of getting gifts from my friends, I would get nonperishable food items from them to donate to the food pantries, because my birthday is around the holidays," said actress Katherine McNamara, "It was always nice to help out right before Thanksgiving."
Of course the festive night's big finale was the cake.
"Thank you to all of my fans and all the people that have been there, supporting me," said Cymphonique. "I just want to say that I love my family, they've set all this up for me. "
"I can't wait until she makes that wish and blow out those candles," said Romeo. "When she blows out the candles, that's when it's official."
