Keira
Knightley
wants
to
be
like
actress
Sienna
Miller.
The
actress
wishes
she
had
the
"amazing" social
skills
of
Sienna,
because
she
struggles
to
think
of
anything
to
say
at
showbiz
parties
and
ends
up
"grinning
aimlessly"
at
strangers.
Keira
is
quoted
as
saying:
"At
parties,
I
stand
on
my
own,
grinning
aimlessly.
I
can
never
think
of
a
thing
to
say.
She
added,
"I
wish
I
was
Sienna
Miller.
I
watch
that
girl
and
she
is
just
fabulous.
She
talks
to
everyone
and
laughs
and
smiles.
She
looks
as
if
she
is
genuinely
enjoying
herself.
When
I
talk
to
her,
I
hope
a
bit
of
her
party
personality
will
rub
off
on
me
but
it
never
does.
She
could
give
master
classes
in
being
the
most
amazing
party
guest."
As
well
as
hating
parties,
Keira
has
also
developed
a
phobia
of
walking
down
the
red
carpet.
The
Pirates
of
the
Caribbean
actress
is
paranoid
she
will
be
ridiculed
for
her
choice
of
dress
at
premieres
and
awards
shows.
Keira,
22,
said:
"I've
become
phobic
about
the
red
carpet
because
you
come
under
intense
scrutiny.
I
always
think
I'm
going
to
make
it
into
the
top
ten
of
some
worst
dressed
list.
I
really
do
try
but
I'm
just
no
good
at
that
stuff."
Keira
is
currently
shooting
new
movie
The
Best
Time
Of
Our
Lives
–
which
was
written
by
Keira's
mother
Sharman
Macdonald
and
is
about
the
life
of
Welsh
poet
Dylan
Thomas
-
alongside
Sienna.
The
'Factory
Girl' actress,
who
plays
Dylan's
wife
Caitlin,
replaced
Lindsay
Lohan
in
the
movie
after
Lindsay
pulled
out
of
the
project
following
a
dispute
with
the
film's
financiers.
Keira
and
Sienna
are
set
to
have
an
on
screen
threesome
with
actor
Matthew
Rhys,
who
will
play
the
hard-drinking
poet.
