According to a report, the ?High School Musical? hunk and the ?House Bunny? babe were recently spotted flirting up a storm while on vacation at Parrot Island.
Of course, Mr. Efron?s camp will only say that Zac and Rumer are ?just friends,? and since nothing is confirmed, this is still very much mere speculation.
Although the fact that Zac recently split with his longtime love Vanessa Hudgens while Miss Willis also parted ways with Micah Alberti does bring up some serious questions.
