Katy Perry dropped some BIG news in her new music video for the single "Never Worn White" -- news that she'll drop a BABY later this year!

The pop star, 35, basically announced she's expecting her first child with fiance Orlando Bloom, 45, and after the clip was released, she took to Instagram Live to say she's "happy and excited" about their bundle of joy expected this summer.

Bloom has son Flynn, 9, with ex Miranda Kerr who's now married to Snapchat billionaire Evan Spiegel.

Rumors now say Katy and Orlando, after having postpone their December wedding, are set to marry in Japan in June?!? Uh ... maybe don't travel so close to your due date to a country with a high number of Coronavirus cases?! Maybe Katy and her man haven't been watching the news.

Surely her OB will advise her to be a bit more careful. And anyway, congrats to the couple!
