From Jennifer Aniston and Justin Theroux to Angelina Jolie and Brad Pitt, look back at couples who put a ring on it in 2012
Matt Lanter and Angela Stacy
After three years of dating, the 90210 heartthrob popped the question in May while he and his love were vacationing in Europe. "They're super happy, and she loves the ring," a source told Us, noting that Lanter personally picked out the diamond-encrusted bauble. "We're kind of homebodies and like to stay home and just enjoy each other, our place and our dog," the actor told Us in October.
