Cheering on Nicole was former X Factor contestant Jahmene Douglas and Hollywood legend Samuel L. Jackson at the lavish Hotel Café Royal in London on Tuesday night (14 October).
Soul singer Jahmene grabbed a selfie with Nicole after her show, and the former Pussycat Doll couldn't have looked happier having impressed the intimate crowd with her incredible vocal range.
After performing 'Don't Hold Your Breath', which was Nicole's first UK number one in 2011, she confessed: "That was so nerve racking!"
Last night marked Nicole's first acoustic show ever, but the former X Factor judge was on good form, showing off her quirky and loveable personality.
"This is my first time performing these songs for real life people!" she declared.
Nicole worked the stage with 'Your Love' and 'On The Rocks', before delivering a spine-tingling performance of 'Run'. She also performed a version of Sam Smith's 'I'm Not The Only One' and praised the singing sensation as "pretty special". We agree!
One person who was clearly blown away by Nicole's performance was Jahmene, who was runner-up on The X Factor in 2012.
After posting the picture, Jahemene said: "Just came from this beauty's private album press launch! And this woman can shaSING!! This next single 'Run' has stunning vocals. So very excited for this album!"
Today, Nicole released an album sampler for Big Fat Lie, giving fans a chance to listen to her album ahead of its release.
