Phillips, 24 years old, met Blackwell while volunteering at the same women's shelter in 2009, according to E!. The two began dating before Phillips became famous as a musician on American Idol.

The musician recently released in May his second studio album "Behind the Lights" and went on a summer tour with Of A Revolution (O.A.R.).

After winning American Idol in 2012, he lauded Blackwell for supporting him throughout.  Phillips said that he loves Blackwell "to death."

In an interview with the Myfm 104.3 radio station, Georgia-born singer shared his story about his first kiss with Blackwell. Phillips said that he asked his girlfriend "Would you mind if I kissed you?" and that Blackwell responded yes.

A source close to the couple told The Hollywood Reporter that Phillips proposed in their new home in Georgia. Phillips told Blackwell to meet him at the house, where he was "down on one knee" when Blackwell arrived.
