Still in the gym: Eight months' pregnant Nicole Kidman and her teeny bump hit the gym for another workout

Gym buddies: Pregant Nicole Kidman and her husband Keith Urban head home after a workout in Nashville Tennessee

The pair are already have a stack of newborn clothes, thanks to gifts from loyal fans.
 
Urban, who recent performed at the CMA Music Festival, revealed last week: 'We got a tie-dyed jumpsuit thing that we really like.'

'We also got a tiny T-shirt that says "I crawl the line" that we like a lot.'

They do know the baby's gender, but the pair have decided to kept it a secret.

Urban added: 'I'm glad we found out though, because it brought it home, you know what I'm saying.'

The country star hopes his wife, who has two adopted children Isabella, 15, and Connor, 13, from her marriage Tom Cruise, will join him on tour after the baby's born.

He says: 'I love having her with me when I tour, but at the same time, it's work. You don't want to ask too much of your family.'

'We'll just have to see what works for us.'
