Pink announces pregnancy with breathtaking Instagram photo.

Stars like Jennifer Aniston can’t eat a big lunch without being accused of being with child, but one celebrity has managed to hide her pregnancy from the ‘bump watch’ paparazzi very well.

US singer Pink announced her pregnancy to the world with a stunning photo uploaded to Instagram on Sunday.

The 37-year-old is pictured outdoors with her five-year-old daughter, Willow, clutching her side, as she gazes into the distance, proudly showing off her baby bump in a flowing white dress.

And that baby bump is not small.

The star fittingly captioned the image, ‘Surprise!’.

Surprise!

Fans certainly were surprised by the news, with the statement ‘OMG’ featuring within many messages of congratulations.

Pink, real name Alecia Moore, is expecting her second child with partner Carey Hart. The couple welcomed their first daughter, Willow Sage Hart, in 2011.

The Daily Mail reported the star had almost avoided pregnancy speculation altogether, with the public only starting to get suspicious when she was snapped in Santa Monica on Friday.

The star was wearing a large blue dress that masked her baby bump, but it was clear that very few people knew just how pregnant she was until she posted her photo on Sunday.

Pink had posted very few photos of herself recently and avoided full-body shots when she did put up a selfie.

Thanks @pamwiggy ????♥️

By chucking in a few throwback snaps from the early noughties of herself, the star managed largely to avoid drawing suspicion for the absence of her torso in photos.

Congratulations to the happy couple and good on Pink for keeping the secret so well.
