After mentoring their remaining hopefuls through Saturday's live shows, the stars looked rather refreshed after leaving a London restaurant at 3am on Sunday morning.
Nicole and Sharon had been dining with Louis Walsh and presenter Dermot O'Leary at Mr Chows, before they left together at the end of the night hugging, kissing and giggling in front of photographers.
Nicole's high spirits were dampened on Sunday night though, as she saw her act Hannah Barrett in a sing-off with Rough Copy and subsequently voted out of the competition.
She argued: "I just can't believe this. These two acts should be in the finals. I am so disappointed and furious with the British public right now that my girl is in the bottom two for the third time."
Nicole comforted Hannah on her shock exit after she'd sung Etta James's 'I'd Rather Go Blind', drying the 16-year-old's eyes and cuddling her as Rough Copy went through to next week's show.
