Jennifer Aniston and Justin Theroux looked a picture of happiness at the Oscars on Sunday (February 24, 2013) and according to a new report, the couple have picked a wedding date, chosen wedding bands and narrowed the all-important dress down to just three choices. Hollywood Life.com say Jen, 44 and screenwriter Justin, 41, will marry soon after she wraps up her current movie in Connecticut on March 8.

"It will be a small affair with their closest friends," a source close to Jennifer tells People, with likely guests thought to include Courteney Cox, Chelsea Handler and Mandy Ingber. The insider says Jen "is crazy about Justin and can't wait to be his wife," adding, "Jen seems more confident than ever and they've become a great team." The couple got engaged on the actor's birthday last August and are often snapped together at L.A. parties or during getaways in Mexico. Nice life huh?

Of course, Jen has done the whole marriage thing before. She tied the knot with Brad Pitt in 2000, though the couple divorced five years later with the actor subsequently hooking up with Angelina Jolie. It doesn't appear to have put Aniston of marriage though, "She plans on privately changing her name to Theroux," said the insider, "She like the way it sounds and jokes that [Jennifer Theroux] sounds very posh. They really seem to have perfect chemistry, like they complete each other. There's a perfect balance. He was doting when she turned to him [at the Oscars], but the overall vibe was simply fun and effortless."

Aniston is currently shooting an untitled crime-comedy by writer Elmore Leonard, about a couple of guys who it off in prison and join forces for one big score upon their release.
