Hailey Bieber feels "so proud" of her husband Justin Bieber following his headline performance at Coachella.

The 32-year-old pop star came under fire from some for his stripped-back set after he sat at a laptop and used YouTube to play parts of his early tunes, such as Baby and That Should Be Me, at times during last weekend's show.

But Hailey is grateful for a "special weekend" with Justin and their 19-month-old son Jack.

She wrote on Instagram: "such a special weekend. nobody will ever know even an ounce of what it's taken to get here. so grateful for this beautiful life. SO proud. let's do it all again!!!! (sic)"

Hailey also shared several backstage images of the trio, as well as her and Jack watching Justin during his soundcheck.

Last summer, Justin dropped album Swag, his first solo record in more than four years, and Hailey, 29, was said to have been instrumental in encouraging Justin to "follow his artistic instincts".

A source told PEOPLE at the time: "Hailey was by Justin's side for the whole creation of the album. Everyone knows Justin as a star and a performer. They now get to know the artist that Hailey has known all these years.

"Hailey supported Justin to follow his artistic instincts. She helped him to trust himself and do what Justin knew he wanted to do as an artist."

Hailey is also believed to have been responsible for encouraging Justin to "run his own show" by choosing the musicians and producers he collaborated with and creating a more "stripped-down" style.

A few months later, Hailey told how she and Justin will always be "very protective" of their son.

She told GQ magazine: "We're just taking it a day at a time.

"We both feel very protective of our son and I don't think that's ever going to change, but our life is our life and it is really public, so I think we're just going to cross every bridge that we need to when we get there. But as of right now, I feel really comfortable about the way we are sharing things and not sharing things."

Hailey also admitted she wasn't fully prepared for motherhood, and doesn't think anyone can be until they have a baby.

She said: "I don't think there's anything someone can tell you about it that will ever, ever, ever prepare you until you do it yourself.

"But I feel much more prepared to do it again, as opposed to how not prepared I felt doing it for the first time. And I think for me personally, there's so much unknown to it, but so much happens and so much changes and you evolve in a totally different way that you would never be able to prepare for until you do it."
