Jennifer Aniston, Justin Theroux Oscars 2013: Engaged Stars Look Ravishing On The Red Carpet (PHOTO)

Megastar Jennifer Aniston arrived at the Oscars tonight (Feb. 24) and looked absolutely glowing in a strapless red gown. Fiance Justin Theroux walked hand in hand with his leading lady, who is also a presenter at tonight's awards ceremony.

Aniston's "Wanderlust" co-star Paul Rudd is also a presenter, as are Salma Hayek, Melissa McCarthy, Liam Neeson, John Travolta, Ben Affleck, Jessica Chastain, Jennifer Lawrence, Halle Berry, Sandra Bullock, Nicole Kidman, Reese Witherspoon, Mark Wahlberg and Ted, and most of the cast of "The Avengers."

Though neither Jen nor Justin is nominated for an award tonight, they have their hands full with their own big day. The couple has been prepping quite vigorously for their wedding and have recently enrolled in "marriage bootcamp," an intense three-day therapy session where they talk about potential problems and share massages.

Aniston has also been busy filming her movie "Untitled Elmore Leonard Project" in Connecticut, where she's been spotted with a platinum blond wig.
