Melbourne, April 12 : Keith Urban's marriage with Nicole Kidman three years ago and his becoming a father to their daughter, Sunday Rose, in July 2008 seems to have left the singer budding with inspiration for his new album.

The country musician sings of happiness and romance in his latest album Defying Gravity, which became his first #1 on the Billboard 200, selling 171,000 copies in its first week of release.

The 41-year-old recalled `My Heart Is Open' was something she had said to him during the early days of their relationship while `Why''s It Feel So Long' held his yearning for his wife after he dropped her at an airport.

Urban, however, insists that despite a glimpse of his family life here and there, the album was not entirely autobiographical.

"For me, writing a lot about anything personal is a difficult balance. On one hand we''re private people, yet on the other hand I write songs that are going to be about my life, my home life, my family," the Daily Telegraph quoted him as saying.

"I guess I write about all that in a way that I''m comfortable. It doesn''t get too detailed or explicit to the point where I feel like my privacy is being invaded, but I''m able to create art from my heart and that is inspired directly by my life," he added.

Meanwhile, his better half was overwhelmed after hearing the love song "Thank You" her country star hubby had written in her honour. (ANI)
