It's splitsville for Jason Mraz and his fiancée.The 'I'm Yours' singer has confirmed he is no longer engaged to fellow singer-songwriter Tristan Prettyman.

He revealed news of the split to The Daily Beast while at the Samsung Hope for Children gala Tuesday night.

"My greatest mistake right now is, I've been clinging to my art," he said. "In that, I have victory for my art and a great loss for my heart. At the moment, my beautiful fiancée is no longer my beautiful fiancée."

Mraz proposed to Prettyman in December, tweeting the happy news, "SHE SAID YES" on Christmas Eve.

No wedding plans had been decided, primarily because the couple decided to wait to tie the knot until marriage was legal for everyone.
