Jennifer Aniston wore a sparkling diamond ring at the Screen Actors Guild Awards. The actress' new ring sparked quite a few rumors about an engagement.

The last time Aniston was in a relationship (or at least one that was publicly known) was with actor Justin Theroux about six years ago. Aniston lost the award in the category in which she was nominated, but she still got to go on stage when she presented the Lifetime Achievement Award to Barbra Streisand alongside the actor Bradley Cooper.
