James Corden has won a Tony award for his hit show One Man, Two Guvnors.
The 33-year-old actor, who found fame in the TV comedy Gavin And Stacey, beat a host of Hollywood stars to the award.
He paid an emotional tribute to his girlfriend Julia - who was in the audience - as he picked up his award.
My girlfriend Julia gave birth to our son five days before we started rehearsals. She is my baby mama and I can't wait to marry her.
Seriously, I would not be holding this if it wasn't for her. She made me say 'us' instead of 'I' and 'we' instead of 'me', and I love her. Thank you very much.
Corden began to well up when he thanked his girlfriend, apologising to the guests and joking:
I'm so sorry, this is ridiculous. It's good that it's not hot in here, isn't it.
Corden won the award for best leading actor in a drama for One Man, Two Guvnors, which was nominated in seven categories.
He said it was a great honour to be mentioned in the same breath as actors such as James Earl Jones, Frank Langella, John Lithgow and Philip Seymour Hoffman.
To be on a list with you was enough and holding this, it honestly just reminds me that there is no such thing as best.
Honestly, I am overwhelmed.
Corden said he shared the award with the show's "brilliant" cast and crew, and thanked producer Bob Boyett, "who took a huge risk bringing this ridiculously silly play to your city". He added:
Your city, the audiences here who have embraced our show like we never ever imagined they could, every night is a joy.
Celebrity friends have tweeted their congratulations to Corden:
Massive big up James Corden on his Tony win, brilliant. Great performance in a great Play. So proud mate. RW.
Huge congratulations to James Corden and his win at The Tony's. The man is unstoppable. I predict he will conquer Hollywood next...
But while Corden celebrated his award, British stars such as Andrew Lloyd Webber and Sir Tim Rice missed out on the Tony award for best revival of a musical.
Despite having two nominations - for Jesus Christ Superstar and Evita - they were beaten to the gong by The Gershwins' Porgy And Bess.
The 66th Tony Awards were held at the Beacon Theatre in New York to celebrate excellence in Broadway theatre.
The stage version of the low-budget Irish film hit Once won nine out of its 12 nominations.
