Emma Bunton insists getting married is not a "major priority".
The 36-year-old singer - who became engaged to former Damage singer Jade Jones a year ago after 10 years together - admits the couple and their children Beau, four and eight-month-old Tate are so close anyway, marriage is not on the cards at the moment.
She said: "We're already a really close-knit family, so it's not a major priority. I'm sure it's something that will happen, but definitely not in the near future."
Despite her loving relationship with Jade, Emma was shocked when Michael Buble confessed to having a crush on her when she was in the Spice Girls.
She told Britain's OK! magazine: "Michael said, 'You used to be my celebrity crush.' I was like, 'Oh my gosh this is embarrassing!' "
However, the 'Stop' hitmaker joked that some of the celebrities she admires failed to echo the sentiment expressed by Michael.
She added: "Johnny Depp didn't say that to me, but I'm sure he was definitely thinking it though!"
