The Westlife star and the singer-and-actress are expecting their first child together and because Jodi can`t drink, Kian has also decided to curb his alcohol intake.
He said: "I haven`t been drinking as much. I`ve had a few nights down the pub but you do go through it together. I don`t like the idea of waking up with a hangover anymore."
Jodi gave up drinking as soon as she discovered she was pregnant but admits she had to pretend she still was during the early stages of the pregnancy so nobody would suspect.
She told Britain`s OK! magazine: "I haven`t missed drinking. Don`t get me wrong, I love a drink and we love going out and having a few cocktails but the minute I fell pregnant I switched off, I didn`t want it. My main concern is growing this baby properly, but because we were out with friends Kian would just order me a soda and lime without the vodka, so people didn`t suspect, and then I`d just pretend I was off my face - I think my days of acting helped out there!
