This clearly hasn't gone down well with 24-year-old Butler, whom 27-year-old Hudgens is dating currently.
Efron and Hudgens had first met on the sets of High School Musical, a Disney original, and had been dating since then.
Efron has been romantically linked to Michelle Rodriguez, Lily Collins and ended his two-year relationship with model Sami Miro in April 2016.And yes, we basically mourned for a couple of weeks when they broke up. However, Vanessa Hudgens has finally opened up to The New York Times about the end of the relationship and surprisingly, we get it. Vanessa Hudgens revealed during Access Hollywood on Thursday, March 23, that she and ex-boyfriend Zac Efron are not on speaking terms. "I completely lost contact with him."Cohost Natalie Morales replied: "Aww, that's too bad." Hudgens and the Baywatch actor, 29, dated from 2005 to 2010 after meeting on set of the Disney TV musical High School Musical. That's not a thing that happens," Hudgens, 28, said, while promoting her NBC series Powerless.You can't really blame Vanessa for feeling a bit jealous, right?
She admitted this jealousy brought out the worst in her, and remembered a period in her life when she let the anger take over.
A source told the website: "Vanessa still has a lot of animosity towards Zac.
He treated her like crap at the end of their relationship."In addition, the actress/ singer also seems to be going pretty strong with her actor beau Butler.
There's only one problem when you're dating one of the world's most sought-after guys, though: the fact that everyone else wants him, too.
Vanessa and Zac got together about two years after their initial meeting in 2005.
In March 2015, Hudgens revealed in a New York Times interview that she wasn't too fond of Efron's female fans at the time, to put it mildly.
