Steve and Martin attended the Emmys after their Hulu comedy Only Murders In The Building received three nominations.
Kieran’s Emmys win was one of four major gongs for the acclaimed HBO drama, which concluded with its fourth season last year.
In his speech Culkin said: ‘I have to thank my manager, Emily Gerson Saines, who I’ve been with about 29 years – sorry Emily, you probably didn’t want me to say the number but I did.
‘I just have to thank you for keeping my name in the conversation when nobody else was talking about me so as far as I’m concerned this is yours.
‘And of course, my beautiful wife Jazz. Thank you for sharing your life with me and for giving me two amazing kids. Kinsey Sioux and Wilder Wolf, I love you so much.
He quipped: ‘And Jazz – I want more. You said maybe, if I win. I love you so much.’
Culkin beat out his Succession co-stars Brian Cox and Jeremy Strong in the category, along with Jeff Bridges – The Old Man, Bob Odenkirk – Better Call Saul and Pedro Pascal – The Last of Us.

Kieran was awarded Outstanding Leading Actor In A Drama Series for his role in Succession, one of four major wins for the acclaimed HBO drama
It was a stellar night for Succession, with the drama also winning awards for Lead Actress for Sarah Snook, 36, before the series as a whole earned top honor Best Drama Series in its final season.
Earlier in the night, Matthew Macfadyen earned the first Emmy win for Succession at the event as he earned Supporting Actor in a Drama Series.
Culkin first shot to fame as a child star courtesy of his older brother and Home Alone legend Macaulay Culkin, now 43 – playing the role of Kevin McCallister’s bedwetting cousin, Fuller in the 1990 movie.
He would reprise this role in the 1992 sequel and play Matthew Banks in Steve Martin and Diane Keaton comedies Father of the Bride (1991) and Father of the Bride Part II (1995) – but seemed destined to forever be in Macaulay’s shadow.
He would once again play a supporting role in iconic teen comedy She’s All That in 1999 as Laney Boggs’ little brother Simon.
His breakout adult role would come as the lead in 2002 film Igby Goes Down – which scored him his first Golden Globe nomination.
He also appeared in the second season of the television adaptation of Fargo.
However it was his role as the youngest Roy son in Succession that would win him critical and worldwide plaudits.
Kieran starred as Matthew Banks in 1991’s Father of the Bride when he was just 11 years old, having previously appeared alongside his brother Macauley in Home Alone
Kieran and Macaulay – along with their five siblings , grew up in poverty, sharing one room in a tiny apartment.
His parents struggled to make ends meet – his dad Kit, a washed up Broadway actor, worked as a taxi driver and a sacristan for a Catholic church, while his mom quit her job to take care of their large brood before eventually landing a part-time gig as a telephone operator.
Kieran later told Vanity Fair of their childhood home, ‘It was barely suitable for a couple [let alone a family-of-nine].
‘It was just a hallway, and there were no separating doors, except for the bathroom, which didn’t have a lock.
‘They raised seven kids in that apartment – for years. They just kept bringing babies home to this little space.’
