Jason Derulo says breaking his neck brought him closer to Jordin Sparks.

The 'In My Head' hitmaker credits his ''amazing'' girlfriend of almost two years for helping him to recover after he broke his vertebrae during tour rehearsals in January 2012.

The 23-year-old singer told E! News: ''The recovery process was crazy too, because as a man, you're just so used to being independent and doing things yourself. Not being able to do things like tie my own shoes or take a shower by myself is pretty humbling.

''It really gave me a chance to get to know myself and really get close to my family and it got me closer to Jordin, which is also really amazing. It really did bring a lot of positive to my life. It gave me a chance to look at my life and decipher what was positive and what was kind of taking up space.

''Jordin was very instrumental in my recovery.

''The simplest things that we take for granted, like tying my shoes or putting on a shirt, she was right there for me. That situation brought us very close because I think it takes a very special person to drop everything they've got going on in their life, especially someone of her calibre, to come and aide me. That was really special.''

Jason previously revealed that he is planning to propose to former 'American Idol' winner Jordin in the near future.

He said: ''The proposal will be monumental. I wrote a song called 'Marry Me'. I have a date in mind. I want to surprise her but she's given me guidelines first. I have to ask her dad for permission.''

Jordin, 23, has been very open about her relationship with Jason and has admitted she would love to settle down with him and start a family.

She said: ''I hope to marry and have kids one day, for sure, and I do see him in my future. But we both have to be ready. If that happens one day, it will happen.''
