FBI keeping a close eye on Amber Heard's Australia investigation

Amber Heard is facing even more legal trouble with word the FBI is

assisting the Australian government as it continues its investigation of perjury allegations.

The 36-year-old is being investigated by Australia's Department of Agriculture,

Water and Environment (DAWE) over whether she lied

under oath after bringing her pet dogs into the country in May 2015.

Heard and ex-husband Johnny Depp travelled to Australia in March 2015,

with the actress bringing their two Yorkshire terriers, Pistol and Boo, along for the trip.

The then couple got into an argument, which resulted in Depp's finger

being severed, however Heard's issues stem from the fact she checked

"no" on her immigration card about importing anything into the country that had to be declared.
