Katy Perry has penned a song for her unborn daughter on 'KP5'.

The 'Daisies' singer - who is pregnant with her first child with fiance Orlando Bloom - has teased a track called 'What Makes A Woman' on the upcoming album, in which she tells her child that there are no ''limits on any of her dreams''.

Speaking to radio station NRJ Lebanon, Katy spilled: ''There is a song on the record called 'What Makes A Woman' that is a hope I have for my future child.

''That she doesn't have any limits on any of her dreams, or what she wants to be, or who she thinks she is and she can change whenever she wants. She can try everything on if she wants.

''I think that song is important to me and important for her.''

The 'Teenage Dream' hitmaker has also named another song called 'Teary Eyed', which was extremely emotional to write.

In an interview with iHeartRadio, she said: ''It's really about just dancing through your tears. And I'm like, 'Wow that really resonates. That slaps, that hits hard for me right now.'

''So I'm excited for it. I'm excited for all of it.''

The 'American Idol' judge has also teased that there are some ''love-based'' songs on her follow-up to 2017's 'Witness' and that the record is '' 75% 'Prism' and 25% 'Teenage Dream'''.

Katy recently explained that the lead single, 'Daisies', took on a new meaning for her amid the coronavirus pandemic, and she hopes everyone else will be inspired to follow their dreams no matter what other people think after they listen to the empowering anthem.

She said: ''I wrote this song a couple months ago as a call to remain true to the course you've set for yourself, regardless of what others may think.

''Recently, it has taken a new meaning for me, in light of what the whole world is experiencing.

''Each of us is one in more than seven billion, with our own story of strength and resilience to tell ... I hope it will be the soundtrack to going for your dreams now ... especially the ones we left behind.''

Katy was planning on dropping her fifth album in June, but it has been pushed back amid the pandemic.
