Stephen Baldwin might have just let the cat out the bag as reports circulate that his daughter Hailey Baldwin has become engaged to Justin Bieber.

The Daily Mail reports that the 'Usual Suspects' star and committed Christian appeared to confirm the reports in a since-deleted tweet in which he said 'Congrats.'

The full tweet reportedly read: 'Sweet smile on my face! me&wife (Kennya) always pray 4 God's will!! He is moving in the hearts of JB&HB, Let's all pray for His will to be done. Love you 2 so much!!! #Godstiming #bestisyettocome Congrats @JeremyBieber.'

Just before that, the Bio-Dome star tweeted the Bible verse John 1:14, 'The Word became flesh and made his dwelling among us. We have seen his glory, the glory of the one and only Son, who came from the Father, full of grace and truth.'

Pop star Bieber and Hailey, a model, have been dating for several months. Both are committed Christians who regularly attend Hillsong Church in LA.

In an interview with The Cut earlier this year, Hailey said the people at Hillsong were like her family. In the same interview, she said that she also sometimes attends City Church, which is pastored by Judah Smith, one of Bieber's closest friends.

She explained the difference in her view between the two church styles: 'City Church is like, where I would bring someone who's never been to church before, because it's a Bible study more than it is a full church service, it's much more relaxed. And I think sometimes walking straight into a Hillsong service can be a lot for someone.'

She added: 'It's a lot. It's a lot. It's intense and it's loud and it's in your face. But I think — it's not for everybody, it's not easy. But I know the people that run it really well, they've become like my family, so that's what I've chosen to go to Hillsong — I do go to City Church, yes.'

Justin has been open about the revival of his Christian faith in the last few years. He was raised a Christian by his mother Pattie Mallette, but drifted for several years as he transitioned to adulthood. In 2015, he was baptized in a bathtub as a sign of his renewed commitment to his faith.

Neither Justin nor Hailey have come out to publicly confirm the reports of their engagement.

But Justin's parents have posted some cryptic tweets in the last few days.

On Sunday, his dad Jeremy Bieber tweeted 'The proudest,' while his mom Pattie tweeted 'Love Love Love Love Love Love Love' before tweeting a few hours later 1 Corinthians 3: 5-6 from The Passion Translation: 'Love does not traffic in shame and disrespect, nor selfishly seek its own honor. Love is not easily irritated or quick to take offense Love joyfully celebrates honesty and finds no delight in what is wrong.'
