Sienna
Miller
and
Keira
Knightley
have
swapped
showbiz
parties
for
board
games.
The
actresses,
who
are
currently
filming
'The
Edge
of
Love'
in
Wales,
have
been
shunning
nights
on
the
town
in
favour
of
backgammon
tournaments.
A
source
told
Australia's
New
Weekly
magazine:
"Sienna
is
big
on
board
games
and
she
has
got
Keira
hooked
too.
They
think
it's
hilarious
because
people
assume
they
would
be
out
on
the
town
every
night
but
instead
they
are
cosied
up
like
a
couple
of
old
men,
getting
all
competitive
over
the
backgammon
board.
"Sienna
says
she
prefers
it
to
a
big
celebrity
party
any
day."
Sienna,
25,
and
Keira,
22,
have
become
good
friends
since
they
were
cast
in
the
movie
about
Welsh
poet
Dylan
Thomas,
which
was
written
by
Keira's
mother
Sharman
Macdonald.
The
film
will
see
the
two
beauties
share
a
steamy
scene
with
co-star
Matthew
Rhys,
who
plays
the
late
poet.
Sienna
recently
gushed
of
her
blossoming
friendship
with
the
'Pirates
of
the
Caribbean'
star.
She
said:
"I
love
Keira.
She
is
so
nice
and
she
gets
me
and
where
I'm
coming
from.
We
always
chat
about
how
weird
the
public
attention
is
and
boys.
"I've
found
a
new
friend
for
life.
I've
had
a
real
blast
hanging
around
with
Keira."
