The singer-turned-fashion designer is expecting her first child with fiancé Eric Johnson and said they've decided to postpone their big day – which was scheduled for November - so that their little one can be there too.
'We were always going to wait [until] after the baby,' she told Us Weekly. 'We flirted around with different dates before I found out I was pregnant, and thankfully we didn't lock anything down. I want to enjoy the day… I'm glad we didn't make a deposit.
'I just didn't want to be stressed out. Now when I get stressed out it's like 50 times worse. So I really want to enjoy that day and now I get to have my baby with me.'
The 31-year-old announced her pregnancy to the world by posting a picture of her dressed as a mummy on Twitter, and thinks that her child will be pretty impressed with how she did it.
'My kid's going to think I'm pretty cool,' she said. 'This is a cool thing to welcome him to the world with.'
