August 2011: Things get serious when Jen and Justin move in together to a Hollywood Hills rental.
February 2012: Jen and Justin become proud parents to Sophie, a boxer-pitbull mix they adopted. "She's the most adorable little cookie you've ever seen," Justin tells New York Magazine. "She looks like she just smoked an exploding cigar."

Apr. 13, 2012: Jen's ex-husband, Brad Pitt, gets engaged to Angelina Jolie. A pal of Jen's tells E! News at the time that the Friends star "doesn't care" about her ex's engagement. "She's happy with Justin. She'll probably marry him. She's moved on. People don't want to believe it, but she has."
