The actress looked stunning Wednesday in her first public appearance as a newlywed at the Los Angeles premiere of her new comedy "She's Funny That Way," but stayed mum on details about her nuptials to Justin Theroux. She wore her ring on the red carpet.
"We had the beautiful luxury of having a beautiful private moment and I'm going to be selfish and keep it that way!" she told ET's Cameron Mathison about the intimate ceremony.
The intimate affair, which was disguised as a 44th birthday party for Theroux, was held in front of 70 of their closest friends and family, including Aniston's "Friends" co-stars Courteney Cox and Lisa Kudrow, as well as Jimmy Kimmel, Howard Stern, John Krasinski, Emily Blunt, Jason Bateman, Will Arnett, Lake Bell, Billy Crudup and more.
The Internet went crazy with speculation about Aniston's wedding dress, but the 46-year-old actress wouldn't spill any secrets.

"I'm not telling you about any of that stuff!" Aniston told ET when asked about her dress. Theroux, by the way, did not attend the premiere as he was in Austin, Texas filming "The Leftovers."
Aniston tied the knot with her longtime love at the couple's home in Bel Air, California, on Aug. 10, after a three-year engagement.
Ellen DeGeneres and wife Portia de Rossi were also among the couple's lucky guests, and DeGeneres couldn't help but gush about the sweet ceremony when ET caught up with her at the D23 Expo last weekend.
"All of it was amazing," Ellen shared. "Jimmy Kimmel was hilarious and Sia sang and that was fantastic. It was just a fun night. It was a beautiful night.
"I love them both and they're both great people and deserve the happiness," she added.
A source told ET that guests at the wedding partied well into the night, dancing to tunes by Michael Jackson, P. Diddy, Rihanna and Jay Z. Aniston's BFF, Cox, was the last to leave the festivities at around 3 a.m., the source added, right after DeGeneres and Kimmel made their exits.
