"Justin Theroux had an amazing birthday on Friday, receiving an extraordinary gift when his girlfriend, Jennifer Aniston, accepted his proposal of marriage," his rep told People. The pair have been together since meeting on the set of Wanderlust in May 2011. For our March cover story, the 43-year-old actress said her joyfulness has increased with her actor-director-screenwriter partner in her life: “Having experienced everything you don’t want in a partner over time, it starts to narrow down to what you actually do want,” she told InStyle. “As I get older I realize what qualities are important in love and what suits me. And what I won’t settle for.” Congrats to the happy couple! See more celebrity engagements! MORE:• Most Popular Rings of the Year• 50 Celebrity Wedding Dresses We Love• Who Got Married Recently?
