The 33-year-old actor took home the Best Leading Actor in a Play gong for his part in 'One Man, Two Guvnors' and admitted he ''can't wait'' to marry partner Julia Carey, the mother of his 15-month-old son Max.
In an emotional speech, he told the audience: ''My girlfriend Julia gave birth to our son like, five days before we started rehearsals.
''She's 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 makes me say 'us' instead of 'I' and 'we' instead of 'me', and I love her. Thank you very much.' ''
Musical 'Once' was the big winner on the night, taking home eight accolades, including Best Musical, and Steve Kazee won Best Leading Actor in a Musical for his performance in the production.
Audra McDonald triumphed in the Best Leading Actress in a Musical category for 'The Gershwins' Porgy and Bess' and 'Clybourne Park' won Best Play.
