The actor admitted his 93-year-old father, Hutton Gibson, to the Clinic in October, where his dad was subsequently diagnosed with kidney failure. Mel's step-mother Joye Gibson has been battling the actor's father in court over claims of domestic violence.

Hutton was admitted to the Mayo Clinic again in January, before traveling to Panama later in the month to receive stem cell treatments.
