Evan Ross' romance with Ashlee Simpson is in the fast lane.
Simpson, the 29-year-old younger sister of Jessica, and Ross, 25, revealed on Twitter Monday that they're now engaged.
"The love of my life said YES!!!!!" tweeted actor Ross, who's starred in TV shows like "90210" and movies like "ATL." The young star included a photo of himself with his new fiancee, who's sporting what looks to be the engagement ring.
Over on her own Twitter account, Simpson just as enthusiastically shared the news that she and her "baby love" are ready to wed.
This will be the singer's second marriage; she was previously wed to Fall Out Boy's Pete Wentz, with whom she has a 5-year-old son, Bronx Mowgli.
Ross and Simpson were first seen hanging out together in July 2013, with the word on the street being that they knew one another "from the club scene and have tons of mutual friends."
They were seen sharing photos of what appeared to be a whirlwind romance, going from cozy one-on-one time ...
... to spending the holidays together.
In November 2013, at that month's "Hunger Games: Catching Fire" premiere, Ross was calling Simpson "the one."
"It’s amazing," Ross told Yahoo! of their relationship. "I’m so in love and we’ve got amazing things going on. And we inspire each other.”
