Evan Ross popped the question to his lady Ashlee Simpson and the two are now engaged.

The singer revealed the news via Twitter along with the first glimpse of her huge rock.

"My baby love and I are ENGAGED!!! Hallelujah Hawaii !!!!!" Simpson, 29, tweeted with a photo of her and Ross.

Ross, 25, also posted the photo on his account with the caption, "The love of my life said YES!!!!!!"

The Hunger Games: Mockingjay star, who began dating Simpson last July, previously boasted about his love for the star.

"It's amazing," he told Omg! Insider in November. "I'm so in love and we've got amazing things going on. And we inspire each other. So, it's cool."

When asked whether or not he would ask Simpson to marry him at some point, Diana Ross' son responded, "Yeah, she's the one."

Simpson was previously married to Fall Out boy singer Pete Wentz and the two have a 5-year-old son, Bronx. She also dated Boardwalk Empire actor Vincent Piazza.
