The 'Sight Of You' singer, 26, performed at London's famous G-A-Y on Saturday night (29 November) and certainly didn't leave her fans disappointed.
Former X Factor judge Tulisa brought the house down when she performed hits old and new - wearing a jaw-dropping outfit!
In a bejewelled bra with matching pants, Tulisa showed off the figure she's been working hard to achieve down the gym.
Wearing fishnet tights and silver boots, a "hyped" Tulisa sang her new single 'Living Without You' which is released in December.
Taking to Twitter before the event, she told her 3.5 million followers: "My first show in 18months #TONIGHT! I'm so excited! G-A-Y You ready?!! #TulisaAtGAY."
During an energetic set, the feisty - or should that be thirsty? - singer was seen downing a pint on set - that's our girl!
After her headline performance, Tulisa tweeted: "OMG G-A-Y that was Insane!!! Thank you."
The next morning she added: "Last night was everything and the audience was 100 per cent!!!! Thank you to everyone that came down! #LivingWithoutYou."
Also performing at the Charing Cross venue were X Factor contestants Stevi Ritchie and Only The Young, both of whom were voted out of the competition last weekend.
Former N-Dubz star Tulisa releases her comeback track on 7 December.
She is making music her main focus after being embroiled in a highly-publicised court case over the past year.
In June, Tulisa appeared in court accused of setting up a drugs deal, however she walked free after the trial collapsed and the judge threw the case out.
She recently admitted: "I remind herself of it every morning that I wake up, as it reminds me of the good times.
"Life is a rollercoaster, the lower down you go, the higher you bounce back up."
