The 19-year-old soprano and Henson, 23, began dating in March (05), a month after Church ended her 11-month relationship with KYLE JOHNSON.
Unlike Church, shy Henson has always been reluctant to discuss their high-profile relationship - until now.
He gushes, "We are getting on really well. We are very serious about each other.
"It feels like we have been together for ages. We are so comfortable with each other and it's great. She is definitely the girl for me.
"There are always stories about us getting engaged or moving in together but at the moment they are not true. She is still so young, we both are."
