Jessica and Ashlee Simpson's dad was spotted snapping photos of his client and friend, male model Jonathan Keith, during Andre Soriano's show at Style Fashion Week L.A. on Monday.
toofab's Anna Kachikyan caught up with Joe after the show to get the details on why he was photographing the runway show.
"One of my models was in the show, and I was shooting. I love shooting," the manager revealed. "In my other life, I was a photographer."
This isn't the first time Simpson has been seen taking photos of the male model.
The divorced dad celebrated his 56th birthday with a long weekend in Miami's South Beach -- playing amateur photographer on the beach as he photographed the 21-year-old.
Joe has shot down speculation that he and the much-younger model were romantically involved. "More mis-information in the news," he tweeted. "The guy in the pics is my modeling Client. He was in Miami taking agency meetings. That's it!!"
