JLS spent £2,500 on dinner for their friends.
The 'Everybody In Love' hitmakers wanted to show their appreciation for the work and support of 15 pals and splashed out the staggering sum for a meal at London restaurant Mr. Chow last night (15.12.09).
A spokesperson for the group said: "They wanted to do it for everything they achieved his year. They invited the whole team who have been working on them."
After leaving the eatery, the quartet - Oritse Williams, Marvin Humes, Aston Merrygold and Jonathan 'JB' Gill - headed to a nearby nightclub to continue their evening.
The group have been regulars on the London party circuit in recent months, with Marvin even catching the eye of 'Russian Roulette' hitmaker Rihanna on a night out at Mahiki last week.
She reportedly told a pal: "JLS are super-talented and super-sexy. It would have been cool if Marvin had come over and said hi.
"Maybe next time. Or if they are ever over in the States we could hook up."
However, Rihanna faces competition for Marvin's affections after he recently confessed to having a crush on Girls Aloud star Cheryl Cole and The Saturdays singer Rochelle Wiseman.
He said: "It's not a secret, I fancy Cheryl Cole because she is beautiful but married, sadly. She is perfect. Me and Cheryl would be great lovers.
"I also like Rochelle from The Saturdays. I saw her the other day and she looked hot."
