Wedding bells are ringing for Ashlee Simpson and Evan Ross, son of Motown icon Diana.
The couple, who are vacationing in Hawaii, announced their engagement on Twitter on Monday afternoon, each posting the same photo with a brief confirmation.
"The love of my life said YES!!!!!!" Ross, 25, wrote; while his future bride took a page from his mother's songbook.
"My baby love and I are ENGAGED!!! Hallelujah Hawaii!!!" the 29-year-old singer tweeted.
The couple went public with their romance back in July when they were seen at a party together following one of Diana's concerts.
The marriage will be the second for Simpson, who was previously married to Fall Out Boy bassist Pete Wentz for three years. The former couple share a son, five-year-old Bronx Mowgli.
