Singer Leona Lewis has said she is "bursting with joy" over her engagement to partner Dennis Jauch.

It was reported in August that choreographer Jauch had proposed to Lewis on their eighth anniversary, and the star has now shared their happy news.

In a post on Instagram, the X Factor winner wrote: "My heart is singing the happiest song it's ever sung!  I'm bursting with joy and overcome with emotion that I get to embark on this new adventure with my best friend..."

"I dreamed you up and you came true," Lewis continued.

"The most caring, kindhearted and inspiring person I've had the privilege to know."

"It's amazing that we were brought together from different sides of the world through both of our passions, music and dance, whilst on tour in the UK eight years ago," Lewis told US celebrity magazine People on Tuesday.

"We are both quite private people, but we wanted to share our happy news with everyone that has supported us and watched our relationship blossom over the years," she continued. 

"We are so thrilled to be on this new adventure together and it is a beautiful feeling to share that love with you all."
