Zac Efron shot to fame via Disney's High School Musical trilogy, after making TV appearances in shows like ER, Firefly, NCIS and Summerland, and performing in plays like Gypsy and The Little Shop Of Horrors. He deferred a place at USC to pursue his acting career, finding love and a five year relationship with HSM costar Vanessa Hudgens, before rumoured romance with Lily Collins. Friends with stars including his The Lorax costar Taylor Swift and actresses Brittany Snow and Ashley Tisdale, Zac's carved out his very own place in Hollywood, graduating from child star to serious adult actor with roles in Hairspray with Nikki Blonsky, 17 Again with Matthew Perry and Leslie Mann, The Lucky One, and The Paperboy with Matthew McConaughey and Nicole Kidman. In his spare time he goes surfing, collects signed baseballs with autographs from the San Francisco Giants, and repairs cars. Needless to say, we love Zac - and here are 25 reasons why!
