Tony Iommi wrote a Facebook post in support of James Hetfield, who recently checked into rehab.

The Metallica frontman announced his stint in rehab last week, forcing the band to cancel its upcoming tour of Australia and New Zealand. This prompted Iommi to post, “My best out to James Hetfield. You’ve done the right thing seeking help – I’m thinking of you, my friend, and wishing you all the very best on your recovery. Looking forward to seeing you back at your best very soon. Your pal, Tony.”
