“He finds them superficial,” spills the insider. “Ben and Jen are at the center of the whole L.A. social scene, which Casey finds frivolous and has really divorced himself from.”
The broody Manchester by the Sea star, 46, “is a guy who’s always searching, reading and writing and trying to figure himself out. The fancy parts of being famous hold no interest to him,” shares the insider, adding that Casey — whose romance with actress Caylee Cowan, 24, is reportedly getting serious — can barely stand the idea of a casual get-together with Ben, 49, and J.Lo, 52.
“Casey is allergic to the circus Ben’s life has become, and it’s just not a world he knows or cares to navigate. He and Caylee won’t be double-dating with Bennifer anytime soon!”
And while OK! previously learned the hot-and-heavy couple called off their 2003 nuptials due to "excessive media attention," Ben and Jennifer are doing little to hide their affection for each other, with the duo often making an entrance any time they're spotted out together.
The A-listers — who first met on the 2002 set of the film Gigli — rekindled their long-lost romance in April of last year following the pop star's split from ex-fiancé Alex Rodriguez.
However, since getting another shot at love, Bennifer 2.0 is making sure they do things right this time around.
The Town actor — who shares daughters Violet, 16, and Seraphina, 13, as well as 10-year-old son Samuel with ex-wife Jennifer Garner — previously reflected on the media frenzy that surrounded the couple back in the 2000s, noting some of the comments made about his brunette babe were "so f**king mean," declaring: "If you wrote it now you would literally be fired for saying those things you said."
Luckily, it seems Ben and Jennifer aren't paying any mind to the haters, as they are pushing full steam ahead with their publicized relationship. OK! recently reported the Justice League star and "On The Floor" songstress bought a new massive $50 million Bel-Air mansion for their blended family. (The songstress shares 14-year-old twins with Emme and Maximillian with ex-husband Marc Anthony.)
The home offers more than enough room to house the former costars and their former flames — and the 13 Going on 30 actress may even take them up an offer to check out their new digs. Ben's ex-wife and new girlfriend have gotten so "close" in recent months.
"They’ve come to an understanding that all that matters at this point is what’s best for the kids. As mothers, this is important to J.Lo that Jen is on board," an OK! insider squealed of the singer's relationship with the father of the actress' children. "Jen’s kids really have taken to Ben and his children which is super important to Jen, too."
