John Hamm, who has had a spot on the "eternal bachelor" list for quite some time, is officially off the market after he tied the knot with Anna Osceola on June 24 in California. The "Mad Men" costars held their wedding at the Anderson Canyon in Big Sur, the same place the "Mad Men" finale was shot. Hamm, 52, and Osceola, 35, became engaged in February after two years of dating. In previous interviews, Hamm revealed that he was "head over heels" for Osceola and was thinking about marriage. "It's only been in the last couple of years, me kind of sitting down and really thinking about all that stuff, that's made the relationship that I'm in now even more meaningful and opened up the possibility of things like being married, having kids, defining a new version of happiness, life, wellness," Hamm said on "The Howard Stern Show" at the time.

Some other "eternal bachelors" who made their way off the list with marriage is George Clooney and Hugh Grant. Clooney, who was considered one of Hollywood's most eligible bachelors, tied the knot in 2014 to human right activist Amal Alamuddin in Italy. The actor originally had "no plans" of ever getting married, but said things changed when he met Amal. "Listen, I didn't want to get married; I didn't want to have kids," Clooney, now a father of two, shared at the time. "And then this extraordinary human being walked into my life, and I just fell madly in love." Another "eternal bachelor" that made their way off the list is Hugh Grant. The actor tied the knot with Anna Eberstein in 2018 after several years of dating. Grant spoke about his marriage on the "Today" show, saying "I should have done it before. I'm just lucky. I'm lucky. I've got a great wife. I love her."
