Perrie Edwards, Jesy Nelson, Leigh-Anne Pinnock and Jade Thirlwall performed at London's famous venue G-A-Y last night (9 November) and Tulisa made sure she was there to support her "little muffins".
After a couple of months away from Twitter, 'Young' singer Tulisa returned to say: "Amazing performance at G-A-Y by @LittleMixOffic."
With their mentor and former judge behind them every step of the way, Little Mix became the first band to ever win The X Factor in 2011. And obviously the girls have remained in touch, as Tulisa spent her Saturday night bopping away to their set.
As the girls performed some of their recent hits, Tulisa could be seen singing out lyrics, waving a Little Mix flag and smiling at fans who recognised her.
Performing new single 'Move', as well as 'DNA', How Ya Doin'?, 'Change' and 'Wings', Little Mix were clearly having a ball - and looked thrilled when they were presented with bouquets of flowers at the end of their energetic performance.
The X Factor contestants Kingsland Road, who left the show during disco week after a sing-off with favourite Tamera Foster, supported Little Mix at the club.
After their exciting evening, they tweeted: "You know you've had a good night when a member comes back with half a tooth!!!! Good one con!! Thanks @LittleMixOffic love you x."
Sounds like a wild night!
