Aussie dad looks VERY disappointed as it's revealed his partner is expecting a baby girl

A father hoping to have a son failed to hold back his disappointed reaction when his girlfriend revealed she was expecting a girl.

The gender reveal party turned from joyous to awkward when the mother burst a black balloon as a crowd of excited friends looked on

The balloon released a flurry of smaller pink balloons and streamers into the sky indicating she was pregnant with a girl.

The father-to-be appeared to verbalise his disappointment at the gender before throwing the remains of the larger balloon on the ground in frustration. 

TikTok user mattyhb92 shared the clip (pictured) on Monday which has been viewed by more than 450,000 people 

The upcoming baby appeared to be the couple’s second child, and second daughter, as the mother was holding a young girl in her arms.

Viewers of the video posted on TikTok were divided over the man’s response to missing out on a son to play catch with in the backyard.

‘His reaction is priceless,’ one wrote.

‘That will be cool when his kid sees this party video in a few years,’ another wrote sarcastically.

‘Be thankful you can have kids,’ added a third.

The father-to-be’s reaction to the revealed gender appears to be less than impressed compared to the other party guests (pictured) 

‘It’s alright, maybe you can share your leggings with her when she’s older,’ a fourth wrote. 

Gender reveal parties have grown in popularity in recent years, despite the inventor of the concept later admitted she regretted it.

They tend to feature a central item which is then opened or set-off to reveal a baby’s gender – usually using the colours pink or blue. 

Such items can include balloons, cakes, smoke bombs, and gifts of varying extravagance.
