Ashlee and Pete- A Timeline
A look back at the couple's happier times.
This afternoon, Ashlee Simpson tweeted that she and boyfriend Evan Ross, 25, are engaged.  The singer/actress/designer and mom to Bronx, 5, showed a picture of the antique-ish ring.

My baby love and I are ENGAGED!!! Hallelujah Hawaii !!!!!” the 29-year-old wrote, while her betrothed posted an equally ecstatic message on his account: “The love of my life said YES!!!!!!”

Simpson, who divorced Fall Out Boy’s Pete Wentz in 2011, began dating Ross in July 2013.  Before that, she was linked to Boardwalk Empire‘s Vincent Piazza.

So, this means that Simpson will become Diana Ross‘ daughter-in-law.
