George Clooney's Baby Pig
Clooney and his pig Max go way back. The actor bought him in 1988 with his then girlfriend Kelly Preston. After the breakup, Max moved into Clooney's mansion as a faithful companion and lived a happy life. After Max's death, Clooney told USAToday that he had no plans to replace Max saying, "I think Max covered all my pig needs."

Max died at the age of 19 (which is more than the average age of a pig, apparently), and Clooney joked that it had been his "longest relationship to date."
