And there was one unlikely guest who was putting a protective arm around the N-Dubber as she left Aura nightclub in London - Myleene Klass' ex.
Tulisa is guided by Myleene's ex Graham Quinn
Graham Quinn left the former Hear'Say singer broken hearted earlier this year when he suddenly walked out on her and their two daughters.
But last night he came to the rescue of Tulisa as the slightly 'tired and emotional' looking judge left the nightspot, helping her to a waiting car.
Tulisa looked as if she'd had a good night
Graham is close to the JLS boys, having acted as their tour manager for many years, and was with them again following their performance on last night's results show, where they sang new single 'Hottest Girl In The World'.
JLS and James Arthur were also seen leaving Aura
Myleene missed out on seeing her pal Rochelle Wiseman of The Saturdays getting hitched to Marvin from JLS earlier this year because Graham was also attending.
