On Friday, the 27-year-old Rhodes founder honored the Peaches singer, who turned the big 3-0, with a touching Instagram tribute.

The model captioned the post, "30!!!!!!!????!!????!!!! that was fast. words could never truly describe the beauty of who you are. Happy Birthday to you. love of my life, for life."

Several of the couple's A-list pals also wished the Biebs a happy birthday in the comments, including Kim Kardashian, who commented, "My couple! Happy Birthday Justin," and added, "the best."

Hailey's moving post follows fans' concern for the duo after her dad, Stephen Baldwin, asked fans to pray for them earlier this week. The two were later seen looking downcast after leaving church.

But it would seem that all is well with the Biebers amid Justin's bday!
