Guy Fieri, Emilio Estevez and others surprise Jeff Ruby during 75th birthday bash

A star-studded birthday bash for a beloved Cincinnati restaurateur took place Wednesday night.

Local steakhouse owner Jeff Ruby celebrated his 75th birthday with a party at the new Jeff Ruby's Steakhouse near Fountain Square. Ruby, who arrived at his birthday celebration wearing a replica of the grey suit worn by actor Clark Gable in the iconic film "Gone With the Wind," told Fox19's Payton Marshall that it started as a simple dinner party but became a Hollywood affair.

"It was a lot of surprises," Ruby said.

Celebrity guests included Food Network chef Guy Fieri, actor Emilio Estevez, legendary blues band The Blues Brothers, sports commentator Marty Brenneman, sports broadcaster Chris Collinsworth, singer-songwriter Lee Greenwood, actor John Goldsmith and more.

Even an old girlfriend showed up, Ruby joked.

"I love the guy and what he does for others. This is a great opportunity to recognize him, and I know he really appreciates it," Fieri told Fox19.

Fieri, a Columbus native, said he timed the filming of "Diners, Drive-Ins and Dives," which took place at The Governor in Milford on Tuesday, around Ruby's birthday celebration. He said it was important for him to show up and be present.

Fieri surprised the guest of honor by arriving at the party dressed as a stunt double with a wig and a visor, yelling, "Mr. Ruby's, Mr. Ruby's, Mr. Ruby's."

"He did not know it was me at all," Fieri said. "I've never dressed up as me being me. Very weird."
