The
delicate
darling
Katrina
Kaif
took
everyone
by
surprise
by
displaying
her
tough
side
while
shooting
for
an
action
sequence
in
her
forthcoming
venture
Ajab
Prem
Ki
Ghazab
Kahani.
If
sources
are
to
be
believed
Katrina
and
Ranbir
were
required
to
climb
a
ladder
which
was
at
a
height
of
200
feet
while
Ranbir
was
to
save
Katrina
from
goons
and
then
escape
on
a
jet
ski.
The
source
goes
on
to
add,
“Everyone
on
sets
was
quite
skeptical
about
Katrina.
However,
Katrina
amazed
everyone
as
she
comfortably
climbed
the
ladder
leaving
Ranbir
lagging
behind."
Ever
since
that
day
Ranbir
has
always
addressed
Katrina
as
Rambo"s
sister
Sambo.
