Jan. 13 (UPI) -- Evan Ross has already described Ashlee Simpson as "the one," so news of their engagement comes as no surprise.
The 25-year-old son of Diana Ross tweeted a photo of himself and Simpson wearing her ring on Monday afternoon, writing, "The love of my life said YES!!!!!!"
Simpson, 29, tweeted the same photo.
