Birthday Girl Victoria Justice: J.Lo is My Role Model! (EXCLUSIVE)

Puerto Rican actress-slash-singer Victoria Justice has a lot to celebrate. Having just wrapped four successful seasons as aspiring singer Tori Vega on Nickelodeon's tween hit Victorious, Justice is also saying goodbye to her teens.

The starlet, who turned 20 on Feb. 19, celebrated Hollywood-style at Sunset Boulevard's chic hotel Andaz West Hollywood with family, friends and fellow celebs including Miley Cyrus, Glee's Chord Overstreet, and Victorious on-screen sister Daniella Monet.

Wearing a silver cutout sequenced dress and black heels, Justice was all smiles when she arrived hand-in-hand with her younger sister Maddy. When she wasn't tearing up the dance floor to Justin Timberlake's "Suit & Tie" feat. Jay-Z and Macklemore's "Thrift Shop", the Fun Size actress was snapping photos with Disney star Debby Ryan and former Zoey 101 costars Erin Sanders and Chris Massey.

"I just want everyone to have a good time tonight and I want to dance until the sun comes up," Justice told us of her birthday wishes.  

As for who's inspiring the 10-year Hollywood vet in this next phase of her career, Justice looks up to fellow boricua Jennifer Lopez.

"Latina role models? I think it's really cool how J.Lo's been able to balance an acting career and a music career," she said. "That's something I strive for."

Justice is on the right path. She's currently in the studio writing her own music for an upcoming solo album.

"I don't have a final date," she said of the album. "I'm going on a big tour this summer to take all the music from the show [Victorious] and I have a big announcement coming up."

Hmmm. What do you think the news is?
