Bennifer, Brangelina go bust: how 'egos clashing' and 'struggle for dominance' can kill Hollywood marriages

Experts explain to Fox News Digital why A-list marriages like Jennifer Lopez and Ben Affleck's and Brad Pitt and Angelina Jolie's can be difficult.

After ending their engagement 20 years ago and marrying other people, Ben Affleck and Jennifer Lopez thought they had reunited for their happily ever after. Their love burned hot, but appears to have quickly gone down in flames. Although they have not spoken publicly about it, they spent much of the summer on separate coasts, and a source tells Fox News Digital, "They are done. Totally done. They are not getting back together."

But Lopez and Affleck aren’t the only power couple to fall apart. Brad Pitt’s marriages to both Jennifer Aniston and Angelina Jolie ended in divorce, as did Meg Ryan and Dennis Quaid’s matrimony, and Nicole Kidman and Tom Cruise's union.
