London,
July
13
(ANI):
'X-Factor'
judge
Simon
Cowell
has
revealed
that
Louis
Walsh
is
so
close
to
the
guest
judge
Nicole
Sherzinger
that
it
seems
he
is
in
love
with
her.
"He's
definitely
in
love.
Seriously
Louis
hasn't
smiled
like
this
for
a
long
time,
he's
like
a
lamb
on
a
spring
day,
I
have
never
seen
him
like
this," the
Mirror
quoted
Cowell
as
saying.
"He
is
so
soft
on
her
it
is
very
sweet.
But
it's
definitely
the
first
time
anyone
has
known
Louis
with
a
crush
like
this.
"It's
like
a
duckling
if
it
is
rescued
by
a
dog
and
the
duckling
then
follows
the
dog
around
thinking
the
dog
is
it's
mother.
"I
mean
it
shouldn't
work
for
obvious
reasons
...
but
it
does,"
he
added.
