Jessica isn't the only Simpson sister getting ready to walk down the aisle!

Ashlee Simpson and her boyfriend Evan Ross are engaged.

The blonde beauty shared a sweet snapshot on Twitter on Monday writing, "My baby love and I are ENGAGED!!! Hallelujah Hawaii !!!!!"

The engagement news doesn't come as a huge surprise, since Ross recently gushed to Us Weekly about his lady love.

"I'm so in love and we've got amazing things going on," Evan told the mag. "And we inspire each other. So it's cool."

The "90210" actor and the "Pieces of Me" singer first stepped out together in early July. They made their public debut as a couple later that month, at the launch of Jessica Simpson's Fall 2013 Campaign in New York City.

Congrats to the happy couple!
