Jessica Alba’s Instagram announcement

When US actress and Honest Beauty founder Jessica Alba announced her baby news on Instagram, it was one of the most adorable pregnancy announcements seen this year.

The mom of two wrote: “@cash_warren and I are officially going to be outnumbered” alongside a short video of her cupping her growing baby bump, holding a No 3 balloon, while daughters Honor and Haven playfully display the numbers one and 2.

Celebrities are increasingly looking for creative ways to break their “we’re expecting” news on social media and the balloon pregnancy announcement seems to be the latest trend that have fans going gaga.

But the trend doesn’t end there. Dubbed megaloons, these novelty balloons come in all shapes and sizes, from numbers to letters to hashtags.

They’ve invaded every aspect of our celebratory lives and Pinterest users are lapping it up.
