The teaser ended with Katy Perry appearing with a rather big belly, surprising fans because not long before, the female singer still appeared with a relatively neat figure.
After the video was released, she took part in an online conversation on Instagram with fans and shared that pregnancy was probably the longest secret she had ever kept.
Rumors about her pregnancy began to spread when Perry shared a few short clips on Instagram, showing her hugging her belly.
On the social network Instagram Live, she once said: "There are many new things coming to me this summer. I am very excited and happy". The Dark Horse singer is said to be 6 months pregnant.
This will be the first child of the 3-year-old singer and her fiance Orlando Bloom. Previously, the actor had a 9-year-old son, personal, with his ex-wife Miranda Kerr.
In many previous interviews, the couple continuously hinted at their grand wedding as well as having children, planning to become perfect parents.
After the news of her pregnancy was revealed, many friends and fans sent congratulations to her and many foreign news sites posted to share the joy with the female singer.
