Kanye West and Kim Kardashian are back in the US after a make-or-break vacation following the rapper’s bipolar breakdown.

The couple touched down in Miami after a weeklong trip to the Dominican Republic. West was reunited with his four kids, North, 7, Saint, 4, Chicago, 2, and 15-month-old Psalm, after being holed up for weeks at his $14 million Wyoming ranch.

Kardashian was seen in tears when she went to see him in Wyoming, as a close source told us they didn’t know if their marriage could survive.

But in the Dominican Republic, West looked happy to be with his kids when he posted video of himself with North on Friday night.

The family vacation comes after the rapper launched an unlikely bid for president in July — and made a string of personal comments about his family and marriage on the campaign trail, which his wife blamed on a bipolar episode.

A source told us: “Kanye asked for a divorce in public, and Kim is concerned about his supposed presidential run, so they have a lot to work through.”
