In May of 2013, he opened up about why he decided to shed some weight.

"I stopped drinking and I just kind of put the weight off...I was having a lot of vodka with sausage...delicious but bad for you," he told Conan O'Brien.

"I was getting into too much trouble with the drinking, so I just kind of stopped," he added.
