New
York
(ANI):
A
source
has
claimed
that
Demi
Lovato
hit
rock
bottom
after
a
fight
with
a
female
dancer
while
on
international
tour
with
the
Jonas
Brothers,
which
ultimately
caused
her
to
check
into
a
rehab.
The
'physical
altercation'
was
the
last
straw
that
spurred
the
18-year-old
Disney
Channel
celeb
-
who
has
openly
discussed
her
past
battles
with
bullies
and
body
image
issues
-
to
seek
help,
reports
the
New
York
Daily
News.
Lovato's
representative
has
said
that
the
actress
checked
into
a
medical
treatment
center
for
"emotional
and
physical
issues
she
has
dealt
with
for
some
time." However,
the
representative
didn''t
elaborate
on
the
specific
problems.
Her
father
told
RadarOnline.com
yesterday
that
he
believed
she
was
overwhelmed
by
life
as
a
pop
star.
One
insider
close
to
Lovato
told
People
magazine
yesterday
that
the
singer
had
recently
become
withdrawn.
"[She]
doesn't
have
that
same
kind
of
love
for
life
that
she
at
one
point
had,"
the
source
said.
Lovato
has
battled
demons
in
the
past,
including
bouts
of
self-mutilation
known
as
"cutting,"
and
an
eating
disorder,
according
to
a
source.
