Jennifer Aniston Explains Why She Loves Justin Theroux

Jennifer Aniston doesn't often open up about her relationship with actor Justin Theroux but recently, the star got all gushy about her fiance during an interview on the red carpet.

Details magazine hosted a party to celebrate Theroux's cover at the Sunset Tower Hotel in Los Angeles on Tuesday night.

A reporter from WWD started chatting to Aniston and was surprised to hear her "let her guard down" when it came to talking about her man.

Speaking about Theroux's role in the HBO series The Leftovers and his appearance on the magazine cover, she said, "I commend him for his courage. This is not normal for him. He's so graceful and utterly kind and golden."

Lovely words, yes - but it gets weirder.

"It is amazing. He's just so beautiful and handsome to me, and I love that his eyeballs are so beautifully captured because those eyes just knock me out every day," Aniston said.

His eyeballs? She continued...

"He just gets better every year. He's just like a lost gem in the sand, and he's just always been there and been brilliant, and now this is just in a different light."

It's a little corny, but you've got to commend Jen on her choice of romantic vocabulary. "Golden," "eyeballs," and "lost gem." It's almost poetic.

In other news, Jennifer has been spending a fortune on her dream Los Angeles home. Find out all the latest below:
