According to an insider, Justin Bieber's reaction when Hailey Baldwin went into cardiac arrest while on his "Justice World Tour" is quite tearjerking - it just proves how much he loves Hailey and cannot stand the thought of her in any health crisis.

Justin Bieber, who is presently on his "Justice World Tour," was devastated when his wife Hailey Baldwin had a medical emergency on March 12. He has been on tour and has been dealing with the regular stresses of putting on a fantastic performance. So when he has down time with Hailey, he makes sure that all the time spent with her is genuine and true enjoyment," an insider close to Justin revealed to Hollywood Life.

The insider said that after Hailey, 25, was hospitalized for a blood clot, Justin grew very anxious, worried, and agitated, especially upon heaving learned what was going on. A blood clot is nothing to disregard, after all.

The medical scare happened to Hailey while she and Justin were out to breakfast in Palm Springs between Justin's tour dates. Bieber panicked over the situation, as many would. He however, clung on to faith to get through.

"There was definitely a lot of praying" over Hailey's health," the source revealed. Now that she is fine and away from the health crisis, the source added that Justin "really feels blessed that she is OK, and he is really happy and if possible, loves her even more."

According to Hailey herself, she was lucky that her body cleared the blood clot on its own, and she recovered entirely within a few hours. Still, it did not mean she was not worried and scared for herself.

He called the incident "one of of the scariest moments I've ever been through" but confirmed that she was now home recovering. "Thank you to everyone who has reached out with well wishes and concern, and for all the support and love," she added.

Since Justin and Hailey's wedding in September of last year, they've been there for each other no matter what. Despite Justin's depressive episodes, his lovely wife has always been there for him. Although their first year of marriage was "difficult," the "Baby" singer revealed to GQ in April that they are still making "wonderful" moments together.
