The untold truth of Zac Efron's new girl, Vanessa Valladares

Zac Efron is a household name, and has been for close to 15 years. Following his breakout role as Troy Bolton in Disney's High School Musical, the actor and heartthrob has done everything from singing in Hairspray to portraying serial killer Ted Bundy in Netflix's Extremely Wicked, Shockingly Evil and Vile. But, as notable as his performances have been, there's another thing for which Efron has received a considerable amount of attention: his relationships. 

Efron famously dated his High School Musicaco-star Vanessa Hudgens for five years, from 2005 to 2010. Having played love interests on screen, Efron and Hudgens' relationship was a constant fixture of the late-2000s pop culture scene. After their breakup, Efron went on to date model Sami Miro from 2014 to 2016 (per E! News). While the actor took a break from dating, at least publicly, after their split, the Charlie St. Cloud actor reportedly has a new boo: Vanessa Valladares. "Zac met Ness earlier in the summer," an insider source told People. "They started hanging out in July and recently took a ski trip together. You can tell that they are having fun. She spends a lot of time at this house." 

Efron's rumored girlfriend is something of a mystery, however. Here's what we know so far.

Vanessa Valladares is an aspiring model from Australia

While actor Zac Efron's past paramours have been well-known public figures, Vanessa Valladares was relatively unknown when she met Efron. The 25-year-old reportedly worked in the service industry before turning to modeling. In fact, according to the Daily Mail, Efron first met Valladares "when she was waiting tables at the General Store café" — a role she soon relinquished to spend more time with her A-list beau, sources suggest.

Valladares now uses her Instagram to share her modeling work. As her follower count continues to rise in the wake of her rumored romance, News.com.au noted that she has already established quite an impressive résumé, as Valladares has worked for Australian labels like Love St, Of The Sun, Spell, and RVCA. Also, the native Australian lives in Byron Bay, which might have inspired Efron's reported desire to ditch Los Angeles and move Down Under.

Yet, for someone dating one of the most famous men in the world, Valladares has done an impressive job keeping her private life under wraps. The model has been conspicuously absent from social media since rumors of her relationship with Efron began swirling over the summer, but that hasn't stopped paparazzi from snapping a picture or two. With or without Efron, Valladares has the world's attention now. What will she do with her newfound fame?
