Birthday boy Zac Efron is set for two surprise parties on Saturday night (18Oct08) as he turns 21.
The High School Musical pin-up is set for one blow-out bash with his Disney castmates and a more intimate celebration with girlfriend Vanessa Hudgens.
The actress is refusing to reveal her plans, but insists her little party won't include clubs or spectaculars.
She says, "We're laidback."
Meanwhile, HSM co-star Ashley Tisdale only hopes she can find the perfect gift in time: "He's one guy who is hard to shop for."
