George Zimmerman Fight Turf War Over Rented Home

George Zimmerman allegedly
punched his estranged wife's father
during a childish dispute over who
had the right to be in the house -- the
renter or the owner, aka George or
his daddy-in-law ... TMZ has
learned.Sources close to Zimmerman
tell us, George and his estranged wife
Shellie Zimmerman have been renting
a home from her parents, but ever
since she filed for divorce they've
been avoiding each other like the
plague -- scheduling house visits
ahead of time to keep the
peace.Must've been a snafu in
scheduling -- because we're told
George showed up Monday AM to
remove some things, and ran into
Shellie and her dad.We're told the
argument erupted when Pops
declared it was his house, and George
replied that he was paying rent ... and
had every right to be there. The spat
ended when Zimmerman allegedly
punched Shellie's dad in the
face.Complicating matters was the fact
George brought his new girlfriend
with him. We're told she was waiting
in his car while he went inside, and
didn't get out until police arrived.At
the end of Shellie's 911 call you can
hear her say, "There's a woman in
there. Oh my god."As for the identity
of George's gf -- we're told she
appears to be someone new ... NOT
George's ex-fiancée, despite what
reports are saying.
