Hip-hop/reggae star Michael Franti is engaged to his longtime girlfriend Sara Agah.

The Say Hey (I Love You) hitmaker took to Facebook.com on Tuesday (20Jan15) and revealed he popped the question to nurse and jewellery designer Agah during a recent vacation to Bali.

Sharing the news with his followers, Franti wrote, "Sara and I are engaged to be married!!! I wrote Life Is Better With You three years ago as a song I hoped to be played at our future wedding and made this video for Sara using clips I shot of her on my iPhone over the past three years. At a surprise dinner I planned in Bali, I played her the song on acoustic guitar and then showed her the video.

"Needless to say she was quite moved and luckily for me after getting down on one knee and asking officially, she said "yes!". Thank you all who have been so kind to us over the years!!!"

Franti also shared a video of his proposal on his Facebook page.

Franti, who has two sons from a previous relationship, and Agah have been dating for six years.
