Jennifer Aniston might be old, but she feels young (and in love)?

Actress Jennifer Aniston, the Generation X role model for women’s hairstyles, has changed men she’s having love affairs with almost as often as she sets a new trend in celebrity hair. But the past year she’s settled down with a man she met at work. While filming Wanderlust, the new movie that is being hyped on television and in YouTube clips everywhere right now, she started up a love affair with the very taken actor and screenplay writer Justin Theroux.

Jennifer Aniston and Justin Theroux are celebrity look-alikesHe had been living with a woman for nearly a decade allegedly when the hair flip – bend and snap moves of fun and flirtatious Jen caught his attention. Several months later, he and the famous actress were living together, the news of his past relationship and split were swept under the proverbial celebrity gossip magic carpet, and the two stars were living together and spending 24/7 joined at the hip, hanging on each others’ arm. That’s right… actress Jennifer Aniston says she’s in love with her man, and his name is Justin Theroux. He’s one of her co-stars in the new movie Wanderlust. And just like Brad Pitt and Angelina Jolie have done for quite some time now when they are out at casual events, they even dress alike now everywhere they go. They have even adopted a new dog together (perhaps to practice parenting together). Isn’t that cute?

[Yes, resist the urge to puke.]

But what caused the super swift hookup? Blame Jennifer’s impulsive behavior on youthful indiscretion. People magazine says, “Aniston – who is known for her age-defying figure – also says she feels young “every day,” but is sometimes surprised by the fact that she’s indeed getting older.”

“You know what makes me feel old? When I see girls who are 20-something, or the new crop of actresses, and think, ‘Aren’t we kind of the same age?’ ” says Aniston.

The aging actress (who is a young and vibrant looking 42-year-old woman and still named as one of the hottest women in Hollywood in nearly every international beauty poll), says. “You lose perspective. Or being offered the part of a woman with a 17-year-old child. It’s like, “I’m not old enough to have a 17-year-old!” And then you realize, well, yeah, you are.”

Knowing her ex-husband and younger actress Angelina Jolie already have six children and are talking about a seventh may have simply been too much of a burden to shoulder for the Hollywood star. While Brangelina rumors were capturing all the attention of the tabloids, the news Jen-Jen might have finally landed a man and started making the necessary lifestyle changes to settle down and have kids of her own seemed to be the only way the actress could continue to remain on the top of charts that list the most talked about Hollywood stars.

If Aniston had not settled down with someone, how many tabloid magazine covers would she NOT be on right now?

Although the actress is joking about grocery store tabloids that say she is pregnant with twins, the thought that her biological clock is ticking loudly right now might not have fully set in.

But Justin Theroux is no dummy. He’s gotten the actress to quit smoking (cigarettes, at least, allegedly). As a celebrity stoner and heavy drinker, Aniston also seems to be tapering off her high school teenage behavior. [She’s not partying up a storm right now, and is spending less time with hard partying friends that she did before say some inside sources who work at places where the stars like to go.]

Will Justin and Jen get matching love quote tattoos and profess their true love always to one another any time soon? After all, she did get a celebrity tattoo of the name “Norman” on her foot… granted it was the name of her dead dog, but still. It did show the actress is ready to make a lifelong commitment.

Hopefully, they will commit symbolically to love soon… because fansite operators are getting gray hair waiting for the celebrity couple to say they are finally pregnant or running away to share their I-do-s. As for early reviews of the movie Wanderlust, the film is not destined to remain in theaters, soon. As one film critic remarked about Jennifer Aniston’s infamous nude scene, “… why do I always get the feeling Jen spends as much prep time on her legs, abdomen, tan and hair as she does on her lines?”

Because, silly movie critics… that’s what the popular teenagers and teen girls do — they spend as much time getting ready to go to school (primping and picking out their wardrobe, worrying about what they look like) as they do come homework time.
