People Editorial Guidelines Published on December 17, 2008 08:20AM EST It’s been a big year for Jennifer Aniston: A new home in Beverly Hills, a new boyfriend (musician John Mayer, 31) and a new comedy, Marley & Me (costarring Owen Wilson), which hits theaters Christmas day. The Hollywood star sat down with PEOPLE to answer questions submitted by readers about life, love, finding happiness – and canine jealousy. How did your dogs [Norman and Dolly] react to your Marley costars? Was there any intense jealousy?– Misti Bell, Bridge City, TexasAniston: Oh, play it for me, Misti! Dolly didn’t travel to Miami because she is too young at 2 ½, and to put her in a trailer didn’t seem fair. All Norman wants to do is just lie at my feet, which is what I like. [The trainers] were strict about letting the Marleys play with other dogs. But there was no jealousy because Norman is very secure. Norman is now 13, but even back [as a puppy] he was as cool as a cucumber. He’s just a person in a dog suit. Do you think you will remarry?– Kizzi Lewellen, Childress, TexasAniston: I don’t know! I honestly don’t know. I’m not against it. Maybe (smiles). Maybe, sure. What have you learned from dating [in the public eye?]– Amy Greene, Murfreesboro, Tenn.Aniston: (Laughs) That if you start to date somebody, by the third date, you can guarantee I’ll be pregnant with twins. What’s your favorite yoga pose?– Erin Tallis, Jacksonville Beach, Fla.Aniston: I’m so terrible with names Child pose. And it’s a mix between that and Tree pose. [Tree] has good balance and I like how it feels. What bad habit do you dislike the most in a man?– Janet Windsor, London, Ontario, CanadaAniston: Janet, let’s see, selfishness. No, that’s a behavior. What’s a bad habit? I’d say forgetting to turn off the lights. Do you carry on any of your childhood holiday traditions? What are some you’ve created for yourself?– Jillian Sexton, Nova ScotiaAniston: My favorite tradition is picking out my tree and then the tree trimming. I just got mine! And there’s eggnog, Christmas carols, usually chili, cupcakes. I’ve cooked the chili – my mom has a great recipe. But now I have a lovely lady cook it because I want people to be happy! Are you looking forward to turning 40?– Marisa Grill, ClevelandAniston: I’m very excited. I had more of a panic going into 30. I think you realize that it just gets better. When they say youth is wasted on the young, it’s so true. Oh my God, what I wish I’d known when I was 30! When you’re having a bad day, what inspires you?– Laurie Pharr, Austin, TexasAniston: You just have to love your life. I have my health, I have my friends, I have my loved ones. I’m extremely lucky.
