1. Shailene Woodley
Shailene Woodley's recent engagement announcement on The Tonight Show With Jimmy Fallon came as a surprise to many of her fans, but in truth, she says she and fiancé Aaron Rodgers had already been engaged "for a while". In a video, the Fault In Our Stars actress can be seen wearing a show-stopping engagement ring that one expert speculates to be "four- to five-carat, solitaire, round-cut diamond set in platinum", costing close to USD100,000.
