The 39-year-old became a dad for the first time when his twin sons Matteo and Valentino were born in August 2008 via a surrogate.
Martin was asked in a new interview with the British newspaper The Guardian if he wants more kids and he added that he would like 'a daddy's girl'.
The star will be playing the role of Che Guevara in the Broadway show of Evita next year and hopes to tie in the job with the birth of his daughter.
He added: 'I'll be steady in New York [next year], and then, after I do the play, the baby [will be] born, and I'm going to be able to spend time with her.'
