Jennifer Aniston at the Oscars 2013 | Pictures

Jennifer Aniston dazzled in red Valentino when she arrived at the 2013 Oscars on Sunday in LA. She was among the many celebs presenting at the Oscars — stars like Reese Witherspoon, Sandra Bullock, and Nicole Kidman all doled out statues last night. Jennifer shared the stage with Channing Tatum and joked with him about the perils of having to get waxed for big-screen projects, a dilemma Channing is familiar with thanks to Magic Mike. Jennifer and Channing presented honors for costume design to the team who worked on Anna Karenina and for makeup and hairstyling to those behind Les Misérables.

After the show, Jennifer and Justin Theroux headed to Vanity Fair's Oscar afterparty at Sunset Tower, where they mingled with A-list pals Chelsea Handler, Miranda Kerr, and more.
