One Direction's Liam Payne and Niall Horan were among the stars who bid goodbye to JLS on their final show ever on Sunday night.
The band - made up of Marvin Humes, Aston Merrygold, Oritse Williams and JB Gill - performed for 20,000 fans at their last ever gig at London's O2 Arena as their farewell tour came to an end.
The One Direction boys took to Twitter after watching the concert with Marvin's wife Rochelle and their seven-month-old daughter, Alaia-Mai.
Niall tweeted: "Jesus! That was an emotional one last night! tears were flowing all round! congrats to the jls lads. What a career! Love u boys. [sic]"
He later posted a picture of JLS sharing a group hug on stage, saying: "That's when I started ballin! [sic]"
Meanwhile Liam tweeted: "Had an amazing night watching @JLSOfficial , amazing guys , brilliant music! [sic]"
Ashton got emotional after the gig and also wrote on Twitter: "That hit me like a f**king hurricane! But Seriously from the bottom of my [heart] thank u! For now I'll say 'see you later' forget goodbye! #love."
The JLS boys ended their set with a cover of Boyz II Men's classic 'End of the Road', having played hits including 'Beat Again' and 'Everybody in Love'.
Fans of band JLS were left heartbroken in April after they announced they were splitting after five years at the top of the music business.
