Jennifer Aniston flashed her massive engagement ring during a spa day in LA on Friday. She dressed up her usual boyfriend jeans with a pair of leather wedges and an oversize Chanel bag. Jennifer is likely taking advantage of her current downtime, as she's been laying low on the West Coast with her fiancé, Justin Theroux. The couple is back on their home turf after attending the Toronto International Film Festival together, where Jen premiered her latest film, Life of Crime, earlier this month. She and Justin are also busy putting the finishing touches on their new home, but most of Justin's stuff doesn't seem to be making the cut. In a recent interview with GQ, Justin revealed that his collection of medical ephemera — which includes a candy dish of human teeth — isn't a favorite of his bride-to-be, saying, "They weren't going to be above the fireplace anytime soon."
