Wolfgang Van Halen has confirmed that Eddie Van Halen attended last night's (Monday, October 21) TOOL concert at Staples Center in Los Angeles.

Earlier today, the VAN HALEN bassist — and Eddie's son — took to his Twitter to post a picture of his father being approached by a TOOL fan, asking the legendary axeman to take a photo of the fan with the stage behind him.

Wolfgang wrote in an accompanying caption: "A guy asked my dad if he could take a picture of him with the stage behind him, having no idea who he just asked, and that was my favorite moment from the @Tool show last night."

There have been a lot of rumors regarding the VAN HALEN guitarist's supposedly worsening health, including a recent report from TMZ stating he is battling throat cancer. According to the gossip site's story, Van Halen has been traveling between the U.S. and Germany for treatment going on several years now. The site later said that "the sad medical news had some folks thinking Eddie was on his death bed ... but we're told that's anything but the case."

As previously reported, Eddie stopped by a McLaren dealership in Beverly Hills on Saturday and mingled with the sales team, taking pictures and even giving one fan a kiss.

A rep for Van Halen had no comment on TMZ's initial report when reached by Fox News.

Earlier this year, rumors were rampant that the classic-era lineup of VAN HALEN would reunite for the first time since 1984. It's unclear why the tour didn't happen, though there has been online chatter that a health setback involving Eddie Van Halen might have been responsible.

VAN HALEN has been inactive since it completed its U.S. tour in October 2015 in Los Angeles, California.
