It's not just champagne linking US diva Mariah Carey and Aussie actor Sophie Monk, who were both invited to the New Year's Eve bash at Jupiters Hotel and Casino at the Gold Coast.
The two have a real estate bond. Monk, a Gold Coast native, is living in Carey's old house in Laurel Canyon, Los Angeles, where she lives when she's not visiting Australia. Carey lived there three years ago with her husband, America's Got Talent host Nick Cannon.
Chatting to S at the singer's first Australian concert at the Gold Coast Convention and Exhibition Centre, Monk joked she was planning to deliver Carey some of her old mail: ''I can't believe I live in the house she lived in only a few years ago. It's surreal!''
Monk has long been a fan of the singer. As a girl with a big voice, dreaming of stardom while she paid her rent singing at Dreamworld, Carey was her idol, she told S.
''I had to come to the show because the little girl in me would never have believed I would have had the opportunity to see Mariah Carey in concert.''
Monk, who is filming two television shows in the US and co-hosting Sea FM summer breakfast radio in Surfers Paradise, was given tickets to Tuesday night's concert by Carey's manager and fellow American Idol judge Randy Jackson.
Monk met Jackson through Idol host Ryan Seacrest, whom she briefly dated several years ago.
They were seen greeting each other in the audience affectionately and tweeting pics with each other.
Jackson dined with Carey and her husband at the Sea Temple's Seaduction Restaurant in Surfers Paradise, where she ate grade 9 wagyu beef prepared by executive chef Steve Szabo.
Carey flew into Sydney last Wednesday night before her Thursday night show and her twins, Moroccan and Monroe, were seen with minders at Darling Harbour's Sydney Aquarium.
The super-cute pair were wheeled out on stage during the Gold Coast concert, where mummy got them to talk into the microphone, introducing them as Roc and Roe and laughing: ''It's bedtime. Night night – I love you, kiss mummy.''
