Justin and Hailey announced her pregnancy just last night (9 May) and fans are in an absolute frenzy with excitement.
The pair took to Instagram to share the exciting news, posting a video along with a series of photographs showing off the baby bump.
Hailey, 27, and Justin, 30, married back in September 2018 after years of on-and-off dating, and it's clear are absolutely buzzing over the latest news of their expanding family.

Now, people are already absolutely loving the adorable detail the soon-to-be parents included in their announcement video as well as pointing to Justin's ex, Selena Gomez's reaction and even praising his first girlfriend, Caitlin Beadle's response.
But the latest chatter seems to be all about the singer's music.
Fans are now all making the exact same prediction about what's to come in a few months - namely that his hit throwback single featuring Ludacris 'Baby' will see itself a renaissance.

The track graced our iPods over a decade back, way back when in 2010, and it's arguably gone down as one of the most iconic career-launching songs in modern pop music history.
People have since rushed to social media to share their prediction with one X, formerly Twitter, user writing: "This song is about too have a resurgence
Congratulations #JustinBieber and #HaileyBieber. Baby Baby Baby!"

A second shared a screenshot of a Google search for 'Justin Bieber baby' which brought up an overview of the song.
They captioned the snap: "Do y’all realise that in a few months there will be VERY different results when you look up 'justin bieber baby'?"
"Justin Bieber becoming a father is crazy," penned a third, "just years ago this was the Baby he had..."
A fourth jokingly chimed in: "Justin Bieber is about to release baby 2.0 feat. Hailey Bieber 14 years after the original."
And it's not just fans having a giggle as there are reportedly official statistics to actually back up the predictions.

A 'Justin Bieber Analytics' page announced: "@justinbieber's 'Baby' is now headed to surpass over a billion streams on Spotify within 100 days, just in time to welcome the Biebers' Baby due around 3 months from now."
And verified Twitter account, StatsCrave, added: "@justinbieber's 'Baby' has started rising on streaming services after he announced that he's expecting his first child with Hailey."
Well, it's clear what will end up being the song of the summer...
Congratulations Justin and Hailey!
