Songfacts®:

• In this song, Keith Urban isn't so sure he can love again, but if he can, he knows he's found the right girl. He wrote the song with Darrell Brown, who also collaborated with him on his 2002 hit "You'll Think Of Me." He said on the country music review site Roughstock: "We've written a lot of things before. I asked Darrell to send me some drum loops. I write a lot from them."
• The Defying Gravity album title comes from a line in this song:
  
  Your heart and mine tonight are defying gravity
  
  Urban explained to Roughstock: "We were in the studio doing some overdubs on the song and as I was listening to the fiddle that was being played, I heard the lyrics going by and especially that line 'defying gravity.' I wrote it down and I realized that's really what this record is about."
• Urban expanded on the album title to CMT News. He said: "It's a very 'up' record, and the record is a lot of that - falling in love and being brave to fall in love - because it takes a lot of bravery to open your heart up and be vulnerable to love. And so it's about rising above things and enduring and not being dragged down. There are a lot of metaphors for that in the title."
• Defying Gravity was Urban's first #1 album on the Billboard 200 chart.
• The inspiration for this song came from a heart-to-heart conversation Urban and Brown had during a lunch break. Brown told People magazine: "We were sitting on a picnic bench talking about the song and about life. It's like group therapy when I'm with Keith."
  
  Urban said he shared something his wife (Nicole Kidman) once said that stuck with him: "Early on when we were dating, she said, 'I'm ready to be brave for us, for you,' and I thought, 'My God, that's what it's about.'"
