Kris Humphries is naked -- well, his wedding finger is.
On Thursday, the NBA player, 26, was photographed leaving a gym in his native Minnesota hometown.
Missing from his post-workout ensemble? The wedding ring he's been wearing since his over-the-top Aug. 20, 2011 wedding to Kim Kardashian.
Humphries was spotted wearing the ring at the same gym on Monday, when Kardashian, 31, filed for divorce after just 72 days.
"I'm committed to this marriage and everything this covenant represents," a stunned Humphries told Us Weekly shortly after the shocking news. "I love my wife and am devastated to learn she filed for divorce. I'm willing to do whatever it takes to make it work."
Counters a Kardashian friend in the new Us Weekly: "Where was he the last few weeks? He wasn't acting like someone committed to giving his marriage a real try."
Humphries was spotted later Thursday afternoon heading into his parents' home.
