It's official: Amber Rose and Wiz Khalifa are engaged.

The model, 28, and the rapper, 24, had been dating for more than one year before he popped the question, according to an Us Weekly report.

Khalifa tweeted a photo of the engagement ring he gave her. It's a pretty simple design, and the rock is quite big.

Rose is tweeting nothing but happy tweets.

This is the happiest Day of my Life, she tweeted recently.

Let's take a quick look down memory lane at some of Rose's more memorable outfits, including the famous one-piece creation she wore at the 2009 MTV Video Music Awards.
