Singer Katy Perry doesn't shy away from showing off her growing baby bump and wearing a crop top.

"Never too pregnant for a crop (top) and never too good for a mask," she captioned a series of her photos on Instagram, reports people.com.

In the first shot, Perry is seen in a white crop top with "Smile" colourfully written on the front and paired with yellow, white and red striped short shorts. In the next photo, she is seen wearing a black "Smile" cap, and a red "Smile" mask in the last.

During a radio show on Sunday, the pop singer talked about various topics relating to her pregnancy and how she is doing -- all while wearing the same crop top she wore in her latest Instagram post.

"I was like, I wanted to wear this piece of merch that I had made for my record, but I was like, 'It's a crop top ... Can I wear that? I'm gonna be a mom,' I was like, 'F--- it! I can still be young and fun and wear a crop top!' " she told the host.

Perry is expecting her first child with actor Orlando Bloom.
