Jennifer Aniston can’t say enough about Justin Theroux -- and his eyes

Jennifer Aniston finds Justin Theroux fascinating -- and if the rare bit of boredom wiggles its way into their togetherness, well, his eye-candy factor kicks in and things get interesting all over again.

That’s how the “Cake” actress makes it sound in a new interview with Harper’s Bazaar, where, in addition to discussing her own success and happiness, she lavishes praise on her multi-talented fiance.

“Not only is he a great actor but he’s one of the best comedy writers out there. And he directs and paints murals,” Aniston told the magazine about the man she named as her creative crush. “And I just think it’s so attractive to be that good at so many things and to have no ego.”

The couple -- who were “buddies” first after meeting during production of 2008’s “Tropic Thunder,” which he helped write, and then costarring together on 2011’s “Wanderlust” -- got engaged in August 2012. No wedding date has been announced.

Theroux’s public profile went a little higher in June with his starring role in HBO’s “The Leftovers,” which led the 43-year-old revealing some startling “secrets” to Jimmy Kimmel a month after the series’ premiere.

“He’s one of the most humble, decent human beings,” Aniston continued. “He’s not an ass. He’s not like some of our friends who are young and up-and-coming and they hit celebrity, and all of a sudden you’re like, ‘Oh! You’re different. Now you don’t say hi to people?’”

Aniston gave him a lot of credit for being able to handle the fact that his fiance is, well, her: America’s sweetheart, whose “narrative is ‘Poor, Sorry, Sad in Love Jen’ ... whatever the stupid headline is.”

She said she’s “detached” from caring about those stories anymore and is simply enjoying her life. (The only bummer about being in her 40s, she said, is that her eyesight is -- um, it’s bad.)

“There was a part of me that used to get very upset. I was guilty of getting too up in arms about stuff that wasn’t real, phantom boxing with something that’s not even there. Now I’d rather just focus on people and things that are here, happening, and what’s yet to come.”

What’s yet to come seems like it’ll involve a lot of Theroux.

“It’s almost impossible to get bored with one another. We’ve tried so hard! And even that’s interesting because his eyes are so pretty,” she said.

“But we can entertain ourselves and talk about endless things, which is pretty great.”

Looks like “Sad in Love Jen” has definitely left the building.
