The disco legends landed the 2,560th plaque on the sidewalk attraction, and surviving members Robert 'Kool' Bell, Ronald Bell, Dennis 'Dee Tee' Thomas and George Brown turned out for a special unveiling ceremony.

Jackson 5 member Jermaine Jackson introduced the Celebration stars ahead of the presentation and praised his pals for their career achievements.

"The release of Ladies' Night and Too Hot in 1979 and Celebration in 1980 led to a non-stop string of million-selling hits," he declared. "Making these evolving superstars the biggest selling band from any genre for the decade of the 1980s, that's an incredible accomplishment.

"The constant rigorous global touring schedule made them the longest-standing constantly touring band in the world. I thought we were! Wow! Doing what they did at 15 years old but doing it better as the years go by."

"So many of you who have helped us through the years, and continue to help us, we thank you," Ronald added to the fans in crowd. "We love you and all of you who love the music, we do too."

"We're very blessed that our music touches people's hearts and their minds, and keeps you dancing and tries to keep you happy on this planet," Dennis added.

The day was extra special for Robert as he also celebrated his 65th birthday on Thursday.
