Miami - Jessica and Ashlee Simpson’s dad was spotted celebrating his 56th birthday on Miami’s South Beach with a 21-year-old male model.
Joe Simpson was taking pics of the shirtless Jonathan Keith while the two were hanging out on the beach together.
Simpson, who divorced his wife Tina in 2010, has denied rumours about his sexuality.
He also hit back at speculation that he and the much-younger model were romantically involved.
He tweeted; "More mis-information in the news. The guy in the pics is my modeling Client. He was in Miami taking agency meetings. That's it!!”
