Justin Bieber says his 'eyes and lips belong' to wife Hailey in gushing birthday tribute

Justin Bieber has declared his eyes, lips and heart "belong" to wife Hailey Bieber in an emotional tribute for her birthday. 

The pop star shared a series of images of the pair on social media, saying his life had "never made more sense" until she became his wife. 

"To my beloved birthday squish. My heart belongs to you. My eyes belong to you, my lips belong to you. I am yours," he wrote in celebration of Hailey's 25th birthday. 

"I am so blessed to be yours. You are my forever. Life has never made more sense until you became my wife. 

"I will never stop loving you, I will never stop holding you, and I will never stop protecting you," he continued. 

"You my queen are more than enough for me and I will spend everyday making you feel like the queen that you are. 

"As your grandma would say in her Portuguese accent 'happy bursday baby' love you until the end of time and then after that." 

Hailey recently opened up about wondering if she could stay with the 'Yummy' hitmaker as he struggled with his mental health, but ultimately deciding she would "stick it out no matter what the outcome was going to be". 

"It was really hard. There were days where I literally was like, 'I don't know if he's going to be okay'," she said during an appearance on the In Good Faith with Chelsea and Judah Smith podcast earlier this month. 

"Something really deep down inside of me was like, 'He's going to get through it.' I just didn't know how long it was going to take. That's what I think was the hardest thing. There's no guarantees."
