Angelina Jolie stepped out of her car and headed into the Roosevelt Hotel in LA yesterday afternoon. She wore a simple dress, carried a YSL handbag, and finished off the look with her new diamond accessory. Angelina debuted the engagement ring, which reportedly cost about $1 million, during a private viewing of the Los Angeles County Museum of Art's Chinese Galleries with Brad Pitt and Pax last week. It was confirmed that Angelina and Brad got engaged when Brad's rep shared that, "It is a promise for the future and their kids are very happy."
