Ashlee Simpson is set to marry Evan Ross after dating since last June.

The son of The Supremes singer Diana Ross, Evan popped the question to the singer on a getaway break to the very romantic island of Hawaii.

The singer tweeted last night; “My baby love and I are ENGAGED!!! Hallelujah Hawaii!!!!!”

Ashlee, Jessica Simpson’s little sister, has a five year old son, Bronx Mogli with ex-husband Pete Wentz of Fall Out Boy fame.

The ring looks to be vintage inspired with a marquise cut diamond. We like it. We like it a lot.
