Lil Jon’s missing DJ son last posted happy photos of himself yukking it up with rapper Bow Wow in Atlanta — just weeks before he vanished.

Nathan Smith, known professionally as DJ Young Slade, hasn’t been seen or heard from since he was spotted fleeing his home near Milton, just north of Atlanta, first thing Tuesday morning, authorities said.

The 27-year-old musician, who disappeared without his phone, has been dark on social media since he shared photos and videos of himself smiling alongside his manager Lil Will and Bow Wow at Atlanta’s State Farm Arena back on Jan. 6.

“Three generations. One culture. Legacy isn’t a moment, it’s a continuum. Young Slade. Bow Wow. Lil Will. Real lineage. Real respect,” he wrote alongside the Instagram photo.

The post came just weeks before authorities blasted out a missing person’s poster in an effort to track him down.

“Subject left on foot and does not possess a phone,” the poster read.

“He may be disoriented and in need of assistance. Family and friends are concerned for his safety.”

Nathan, whose latest single “Feels” dropped last March, is one of Lil Jon’s two kids.

“The family is asking for privacy at this time,” a rep for Lil Jon said.
