Channing Tatum and Zoë Kravitz will NOT be walking down the aisle … they are throwing in the towel on their relationship … and calling off their engagement.

The actors are splitting after 3 years together … TMZ has confirmed.

Channing and Zoë got engaged last year, but Zoë had been spotted in public recently without her engagement ring … though it’s unclear when, or why, they broke up.

The exes began dating in 2021 and even worked on a new movie together, “Blink Twice” … with Channing in a starring role and Zoë behind the camera for her debut as a director.

Channing and Zoë actually got engaged around this time last year … with Channing popping the question just before Halloween, and Zoë showing off the ring when they went out to a costume party.

They were both going through divorces when they became an item … and, Zoë has since settled her divorce with Karl Glusman, and Channing recently settled his divorce with Jenna Dewan.

We saw Channing out on a run back in September with Zoë’s initials inked on his hand … which we took as a sign of affection … but something’s obviously changed.

PEOPLE was first to report the split.

We reached out to reps for Channing and Zoë … so far, no word back.
