Keith Urban gives an insight into his marriage, says wife Nicole Kidman is a 'maniac' in bed

Nicole Kidman's dirty secret might just be out, as her husband of almost 13 years revealed it in his latest song, 'Gemini', that his 51-year-old wife is a "maniac in the bed'.
The 51-year-old country singer, Keith Urban, admitted that the NSFW lyrics from his track 'Gemini' on the 2018 Graffiti U are indeed about his wife, Nicole Kidman. The four-time Grammy winner had added the lines, "She’s a maniac in the bed / But a brainiac in her head / And I know that everybody knows / Ooh, that she’s both."
Urban confessed during an interview with iNews that it was while writing the song along with Julia Michaels that he began to describe his wife, who certainly loves the song herself. He stated, "It’s a fun song. My co-writer Julia Michaels asked me to describe Nicole and that’s what came out. ‘She is Gemini, but she’s not a contradiction.
She can roll with things.’” He continued, "The song is actually about Nicole – and she loves it.”
