He told Hello! magazine: ''My only dream is they look like her.''
The '30 Rock' star already has a 16-year-old daughter, Ireland, whom he fathers with ex-wife Kim Bassinger and he feels extremely glad that Ireland gets along well with his new wife.
He added: ''My daughter is as in love with her as everyone else.''
The 54-year-old admitted that he was lucky to be able to get into a romance with Hilaria. He gushed, ''I'm happier when I'm with her. I'm not as happy when I'm not with her. Let's face the facts: I got lucky.''
Hilaria also revealed that she loves being married to Alec and has never been as happy.
She said: ''Being married is pretty incredible. To look at a person and say, 'I'm going to spend the rest of my life with you' feels wonderful.''
