Zoë Kravitz's stepdad Jason Momoa and boyfriend Channing Tatum support actress ahead of movie premiere

Jason Momoa has shown his support for stepdaughter Zoë Kravitz amid claims he has reunited with her mother, actress Lisa Bonet, months after their shock split.

The Aquaman star, 42, shared photos of himself and Kravitz's boyfriend, Channing Tatum, en route to a premiere of her movie The Batman. 

"CHEEEEHUUUUUUUU. SO EXCITED @channingtatum and I are on our way to see our ZOZO. finally @thebatman premiere," Momoa captioned a photo of himself and the Magic Mike star posing on a tarmac.

Tatum looked just as excited to support his girlfriend, 33, at her movie premiere. The pair reportedly met on the set of the upcoming thriller, Pussy Island. The film will be Kravitz's directorial debut — she also co-wrote and co-produced the movie, of which 41-year-old Tatum stars.

Meanwhile, Momoa's show of support comes amid claims he has reconciled with Kravitz's mum. The actor and 54-year-old Bonet — famous for her role in The Cosby Show — were together for 17 years, four of which they were married.

However, a source tells Hollywood Life they may be giving their marriage another shot and are "already living together again".

"Jason moved back in with Lisa about two weeks ago and they are very much back together," a source claimed to the couple, who share two children together: daughter Lola, 14, and son Nakoa, 13. 

"They decided to work on things rather than throw in the towel because they have so much invested in each other." 

It appears a statement announcing their split back in January, which Momoa had posted to Instagram, has now been deleted from his account.

"We have all felt the squeeze and changes of these transformational times. A revolution is unfolding and our family is of no exception," he wrote at the time.

"Feeling and growing from the seismic shifts occurring. And so we share our Family news that we are parting ways in marriage. We share this not because we think it's newsworthy, but so that as we go about our lives we may do so with dignity and honesty," he added.

"We free each other to be who we are learning to become … Our devotion unwavering to this sacred life & our Children Teaching our Children What's possible Living the Prayer May Love Prevail J & L."
