Melbourne
(ANI):
High
School
Musical's
Zac
Efron
may
have
left
his
Sydney
fans
gasping
when
he
was
spotted
sunbathing
with
his
co-actor
girlfriend
Vanessa
Hudgens
in
the
Harbour
city.
The
20-year-old,
who
arrived
in
the
city
ahead
of
the
Disney
franchise's
premiere,
was
reportedly
seen
flexing
his
muscles
while
his
love
interest
and
'High
School
Musical
3'
co-star
Ashley
Tisdale
clenched
hands
during
a
short
water
taxi
ride
back
to
their
hotel.
Dubbed
as
'the
new
American
heart
throb'
by
the
Rolling
Stone
magazine,
Efron
is
said
to
have
insisted
on
categorising
himself
as
a
'serious
actor'
despite
his
young
appeal.
The
actor-singer
also
scored
brownie
points
when
he
impressed
fans
with
his
voice
in
the
film
version
of
the
Broadway
musical
'Hairspray',
reports
the
Daily
Telegraph.
