Hamm finally took home the best actor gong after seven years of nominations and disappointment.
Jon Hamm has finally won his Emmy.
The Mad Men star - who has been nominated seven times for his role as Don Draper in the AMC show - scored the Emmy for outstanding lead actor in a drama series, but managed to trip over on his way up to the stage.
Composing himself and collecting his Emmy from Tina Fey, he said: "There has been a terrible mistake clearly. It is impossible to named with all those extraordinary gentlemen, it's impossible to be up here and to have done this show with these incredible people.
"It's incredible and impossible for me personally to be standing here so I want to thank the people I owe an incredible debt, families who have chosen for some reason to take me in and be nice to me.
"Thank you to everybody who watched the show and thank you for this."
The happy win comes weeks after the actor announced his separation from long-term partner Jennifer Westfeldt.
The Mad Men actor and his actress girlfriend called time on their relationship but have vowed to continue to be 'supportive of each other'.
In a statement to UsMagazine.com, the pair said: "With great sadness, we have decided to separate, after 18 years of love and shared history.
"We will continue to be supportive of each other in every way possible moving forward.”
Jon, 44, met Jennifer at a party in 1997 and they began dating. However, it’s claimed the pair haven’t been on the same page recently.
A source said: "They've been fighting for a while, but now they're done. They decided to finally split. It's sad."
Earlier this year, Jon completed rehab for alcohol abuse ahead of the final season of critically lauded Mad Men .
After finishing a 30-day stint in a treatment centre, Jon credited Jennifer, 45, with helping him overcome his addiction .
The actor’s representative said at the time: “With the support of his longtime partner Jennifer Westfeldt, Jon Hamm recently completed treatment for his struggle with alcohol addiction. They have asked for privacy and sensitivity going forward.”
The TV hunk and his partner previously spoke of their decision not to have children together.
In 2011, Jon said: “I have a tremendous amount of respect for my friends who do balance this particular career with raising a kid, 'cause it's a tricky environment to bring them into... So not for us just yet.”
