Vanessa Hudgens sometimes finds herself singing the High School Musical songs.

The 27-year-old actress shot to fame starring as Gabriella Montez in the first Disney Channel movie back in 2006, before reprising her role for 2007's High School Musical 2 and High School Musical 3: Senior Year in 2008.

Vanessa has now moved on from the franchise, but often finds herself humming some of the films' catchiest tunes.

"(I sing them) every now and then. Sometimes, someone will be like, ‘We’re all in this together,’ and then I’ll be like (starts singing), ‘We’re all in this together!'” she laughed to Entertainment Tonight, referring to the finale song from the first movie. “It’s like reflexes.”

Vanessa's next role sees her starring in NBC comedy Powerless, which tells the story of an insurance firm who are left with the task of cleaning up the messes of superheroes.

And she has also been using her High School Musical past to influence karaoke nights with her new castmates.

"We did a High School Musical song, Breaking Free," Vanessa said, talking about the duet she and then-boyfriend Zac Efron performed in the first film.

“I was like, ‘This is so funny because I saw my name (in the karaoke song book), but it was Vanessa Anne and that was it. I was like, ‘OK, that’s interesting.’ So naturally, I had to sing myself."

The franchise is now being given a revival, with Disney Channel currently casting for High School Musical 4. Vanessa is thrilled that an entirely new generation will be able to experience the joy of the story.

“I love musicals. Being able to do musicals is such a dream of mine and the fact that they’re keeping it alive and bringing it to a new generation is really wonderful,” she added.
