Courteney Cox ‘Urging’ Longtime Friend Jennifer Aniston to ‘Be Careful’ With New Beau Jim Curtis

Joyful Jennifer Aniston is head over heels for brand-new beau Jim Curtis — but concerned pals, including former Friends castmate Courteney Cox, are begging the beauty to take things slow to avoid yet another heartbreak if the fledgling romance doesn’t stick, sources say.

“Courteney has seen Jen get hurt over and over, and she doesn’t want to see the past repeating itself. She’s urging her friend to be careful,” an insider explains.

The Morning Show star, 56, has seemingly thrown caution to the wind with the 49-year-old wellness coach and hypnotherapist.

“Jim is charming and charismatic — but some of his past behavior has raised major red flags,” the insider shares.

In his 2017 book, The Stimulati Experience, the guru documents his own health journey and details his advice for overcoming pain, stress and personal setbacks.

The father of one writes about a time when he lacked meaningful relationships and flitted from one fling to another. He also shares that he wished he got along better with his son and calls his “high intensity” sister a “pain in the ass.”

The insider notes, “He’s been very open about the fact that he’s struggled to keep a relationship because he gets bored easily. Apparently, even his ties with his own family are strained, so, of course, alarm bells are going off for Jen’s friends.”

Some pals even fear that Jim may be using the Hollywood power player to bolster his image.

“Courteney and others are telling her to pump the brakes and really get to know this guy before she hands over her heart,” the source confides.

“But they’re already joined at the hip, which is typical of Jen. She tends to go all in very fast and is very trusting.”

The longtime sitcom cutie, who was previously married to actors Justin Theroux and Brad Pitt, was spotted canoodling with Curtis in Spain — days after the duo shared a cozy dinner in Big Sur, Calif.

The source says, “Jen is in a good place in life. The last thing she needs is another guy bringing drama — or using her to boost his own career.”
