Things are heating up: First it was double dates. Then public displays of affection
Now, Jennifer Aniston
is mixing business with pleasure by bringing new beau
Justin Theroux to her interview with James Lipton for Inside the Actors Studio
Theroux, 39, "was sitting in the front row, and she made eye contact with him," second-year Actors Studio MFA student Christina Schudel told PEOPLE at Thursday's New York taping with Aniston, 42. The interview will air next month on Bravo.
"Whenever there would be a lull, she would just look at him and give him a wink and go back to what she was doing," says Schudel.
Aniston was also clearly a hit with the crowd – which roared with laughter after Lipton asked what drew the actress to the 2006 movie The Break-Up
Replied Aniston: "Well, you know it's something I have a lot of experience with."
"She was just so relaxed and so open," observed Schudel. "So lovable from beginning to end. Such a sweetheart."
Lipton, who chatted with the Horrible Bosses
star for nearly three hours, says he was completely captivated by Aniston's warm personality.
"She's as quick and witty and charming as she is on screen," Lipton told PEOPLE immediately after the interview.
Among Lipton's questions and Aniston's answers:
What turns you on?
"Generally or currently?" she said with a laugh as she placed her face in her hands and shook her head. "A great pair of shoes" – prompting Theroux to laugh and applaud.
What turns you off?
What's your favorite word?
"Norman," said a slightly teary Aniston, referring to her 15-year-old Welsh corgi-terrier mix, who died in May
What's your least favorite?

"A baby hysterically laughing."
What sound do you hate?
What profession other than your own would you like to attempt?
"Attempt is a good word ... interior design."

"Be the President."
If heaven existed, what would you like to hear God say to you at the Pearly Gates?
"Never thought I'd see you here."
