Hailey Bieber has denied "funny" speculation that she is pregnant

Hailey wrote: "The internet is funny!! No, I'm not pregnant I just really love food."

Meanwhile, Justin, 25, recently celebrated Hailey's 22nd birthday with a sweet social media post and insisted that babies are in their future.

He wrote: "Happy birthday babes! You make me want to be better everyday! The way you live you life is so attractive.. ps you turn me on in every way. next season BABIES (sic)."

Justin previously opened up about how childhood fame had left him feeling suicidal and using "pretty heavy drugs" but said marriage to Hailey has changed his life for the better.

He wrote on Instagram: "It's hard to get out of bed in the morning with the right attitude when you are overwhelmed with your life, your past, job, responsibilities, emotions, your family, finances, your relationships. Sometimes it can even get to the point where you don't even want to live anymore... By this point I was 18 with no skills in the real world, with millions of dollars and access to whatever I wanted. This is a very scary concept for anyone. By 20 I made every bad decision you could have thought and went from one of the most loved and adored people in the world to the most ridiculed, judged and hated person in the world ... It's taken me years to bounce back from all of these terrible decisions, fix broken relationships, and change relationship habits. Luckily god blessed me with extraordinary people who love me for me. Now i am navigating the best season of my life 'MARRIAGE' !! Which is an amazing crazy new responsibility. You learn patience, trust, commitment, kindness, humility and all of the things it looks like to be a good man. All this to say even when The odds are against you keep fighting (sic)."
