Figueroa has been working non-stop to keep his father's legacy alive after the beloved star passed away following a long battle with bone cancer in July (15).

Figueroa promoted a previously unreleased track from his father days after Sebastian's passing, and he recently organised a star-studded benefit concert in their native Mexico in honour of his dad.

However, the job finally caught up with him as Figueroa was admitted to hospital over the weekend (ends23Aug15) suffering stress and chronic fatigue.

He took to Twitter.com to post a note from his doctor, writing, "By Doctor, body and soul's orders, a well needed rest."

According to LatinGossip.com, Figueroa's doctor advised his patient to see a specialist in order to help him cope during the mourning period, in an effort to not affect his health.
