Selena Gomez Gets Justin Bieber 'Love Advice' From Jennifer Aniston After Break-Up? Starlets 'Bond' Over Dinner, 'Spiritual Healing' & Potential Project RUMORS

Apparently, former "Friends" starlet Jennifer Aniston is taking on the role of Selena Gomez's older and wiser role model!

The two Hollywood beauties shared a lovely dinner together in LA on Saturday (May 17). Throughout the meal at Madeo, eyewitnesses insist that Aniston was busy sharing some relationship advice with the 21-year-old "Come & Get It" songstress.

Gomez went through a lot of heartache after her highly-publicized break-up with fellow pop sensation, Justin Bieber. Obviously, Aniston isn't shy to similar heartbreak - she divorced ex-hubby Brad Pitt back in 2005, after he pursued a romantic relationship with "Mr. & Mrs. Smith" co-star Angelina Jolie. Thankfully, Aniston is now involved in a happy and healthy relationship with actor Justin Theroux.

Anyway, a HollywoodLife.com insider reveals:

"Jennifer was definitely giving Selena love advice. I overheard both of them say Justin's name and Jennifer was doing most of the talking and Selena was doing a lot of nodding... They were pretty much talking to each other the whole time, while the two guys were in their own conversation." 

Another source claims that the two ladies were involved in a private discussion for two hours, tucked away in a back corner of the restuarant with two other unknown male diners.

"They were talking, they were laughing, they seemed to be really into the conversation. As for the guys they were with, one was younger (in his 20s), and the other was a middle-aged man (he looked like an agent). It definitely wasn't Justin [Theroux]. They ate a full dinner and they looked like they were having a really good time." 

Rumors suggest that Gomez and Aniston were perhaps even discussing the potential of working on a "future project" together - that sounds pretty cool!

Before parting ways, the 45-year-old actress left Bieber's ex with a very sentimental gift. 

"Jennifer had a book with her sitting on the table called A Return To Love and she gave it to Selena before they left," the insider continues. "I recognize the book, it's by Marianne Williamson and focuses on spiritual principles and loving yourself. It was like Jennifer was her big sister." 

So, has Gomez's BFF Taylor Swift been replaced with a new (more mature) mentor? Hopefully Gomez takes such advice to heart, so she'll be able to move past her first love!
