Meanwhile, the 'No Air' hitmaker revealed she'd been wearing her husband's clothes became she hadn't had time to purchase any maternity wear.

She shared: "For the past month, it's been this in-between stage where I've been taking a hair tie and clipping the hole of [my] jeans onto the little buckle.

"It kind of helps open them a little bit. Then that stopped working and I was just like 'Babe, can I wear your sweatpants?' I've been wearing his sweatpants all the time!"
