Speaking to Associated Press, the British actor explained that he is in “awe” of the singer.
“It’s been really impressive there’s been no complaining,” Bloom said.
“She’s just been all about it. It’s pretty awe-inspiring the way she handles herself, the way it’s business as usual.”
Bloom added that “aside from a giant belly” you wouldn’t know Perry was pregnant.
“You wouldn’t know. She’s a force of nature, obviously. As we all know, as everyone knows.”
Perry announced she was expecting her first child with Bloom in March.
The singer unveiled her bump in a music video for her single Never Worn White.
Bloom’s comments come after Perry revealed she considered suicide in 2017, shortly after a split from Bloom.
“My career was on this trajectory when it was going up, up and up and then I had the smallest shift, not that huge from an outside perspective. But for me it was seismic,” she told radio station SiriusXM CBC.
“I had given so much out, and it literally broke me in half. I had broken up with my boyfriend, who is now my baby daddy-to-be.
“And then I was excited about flying high off the next record. But the validation did not make me high, and so I just crashed.”
Perry explained that gratitude helped her heal at the time.
“Gratitude is probably the thing that saved my life,” she said.
“If it gets really, really hard I walk around and say, ‘I am grateful, I am grateful!’; even though I am in a sh***y mood.’’
