Brandon Routh and wife Courtney Ford are expecting their first baby.
The 'Superman Returns' actor and his partner - who have been married since November 2007 - found it hard to keep it a secret, and he admits everyone on the set of his new pilot series 'Partners' has been asking him about it.
He told People.com: ''Everyone on set keeps asking, 'Do you have kids?' And I've had to say, 'Well, not yet!' It's the truth. The baby hasn't been born yet!''
Courtney confesses she was having to lie about her medical condition and is glad to be able to finally tell the truth to her co-stars on 'Parenthood'.
She said: ''It started getting difficult to hide what was happening. Flu and food poisoning excuses only work for so long, and by the last episode I could no longer button my pants! I just tried to joke that I had a big lunch.''
Brandon and Courtney met in 2003 when he was working in a bar, but he has since gone on to star in 'Scott Pilgrim vs. The World' while she has appeared as Portia in 'True Blood'.
