JLS' Jonathan J.B. Gill was drowning his sorrows about the band's split at Playboy Club London last night (30.04.13).

The boy band announced they will go their separate ways after a farewell tour and greatest hits album 'Goodbye' in December, and Jonathan was seen enjoying the launch of their new cabaret show at the venue's Baroque bar.

He was joined in the exclusive night spot by a host of stars including rapper Professor Green, pop duo Rizzle Kicks, model Amber Le Bon and reality TV star Lydia Bright.

Green started off the night well, promising his personal trainer, Rich Tidmarsh, not to overindulge, writing on Twitter: ''Sorry baroque, it all looks outstanding but richtidmarsh wouldn't be impressed (sic).''

However, it seems later he may have broken his promise, tweeting: ''The most love to @cocktailmaestro and @joncalabrese. Always ruining my dreams of sobriety (sic).''

He followed it up this morning by writing: ''I know I was there. Ouch.''

The celebrity guests indulged in a champagne towers and entertainment from The Baroque Cabaret Troupe,a seductive tango duo, a sword swallower, and a trio of dancing Kittens in an evening's entertainment which was hosted by self-proclaimed 'King of Light Entertainment', entertainer Lenny Beige.

The Cabaret Troupe at Baroque at Playboy Club London launches tomorrow (02.05.13).
