Most said, ‘Happy birthday Justin!’ but many others were shocked he has gotten to this age already.

‘Bro, 30 already? How can it be? Last time I looked you were like 21,’ said one fan.

Others asked for him to work harder: ‘Where is the new album?’ asked one while another joked: ‘Justin we don’t want much just a world tour!’

And there were several sweet stories like this one: ‘Happy birthday Justin, many years of more and more lives for you, I’ve been following you since I was nine years old and today I’m almost 24 and I say and repeat thank you for existing, I’m very grateful to be your fan.’

This comes after his wife Hailey Bieber‘s father Stephen Baldwin asked fans to say a ‘little prayer’ for his daughter and son-in-law Justin.

Justin Bieber turned 30-years-old on Friday. And fans went wild with the milestone after having grown up on the singer cranking out hits for teens like Baby and Sorry. His followers flooded his Instagram account with well wishes

Hailey is reportedly ‘pissed’ at her actor dad.

Sources close to the Vogue model told TMZ that she and Justin are going through a ‘private’ family matter at the moment.

Dad Stephen has been aware of the issue, and felt he needed to hint to the world there were problems.

It is not known if the trouble has to do with their relationship or health but the actor did share it had to do with ‘marriage and faith.’

Hailey has publicly ignored her father’s call for prayers.

Stephen raised eyebrows when he reposted a video of Justin singing, which was shared by All Things Possible Ministries founder Victor Marx.

He captioned it: ‘Christians please when you think of Justin & Hailey, take a moment to offer a little prayer for them to have wisdom, protection, and draw close to the Lord.’

The 58-year-old evangelist also wrote that his wife Eileen Marx and Hailey’s mother Kennya Deodato Baldwin ‘pray often together’ for the married couple, who wed in 2018.

‘There are special challenges that folks in high visibility positions face and also the enemy doesn’t want them to draw closer to Jesus,’ Victor wrote.

‘So often regardless of the material things or the accolades they often face spiritual warfare that [is] intense and seeks to ship-wreck their faith, marriage, and life in general. So thank you.’ Marx has since deleted the post.

Justin and Hailey were seen this month at Erewhon in Los Angeles making one of her shakes.
