Josh Duhamel to star in 'Shotgun Wedding' with Jennifer Lopez after Armie Hammer exits film

Josh Duhamel will step in to star opposite Jennifer Lopez in "Shotgun Wedding," after Armie Hammer dropped out of the film in the wake of multiple abuse allegations.

Lionsgate, the studio producing the upcoming comedy, announced the casting update in a press release Tuesday.

"We couldn’t be happier for our bride and groom of this 'Shotgun Wedding,' " Erin Westerman, the president of production for the Lionsgate Motion Pictures Group, said in a statement. “We know Josh and Jennifer will make a compelling and sexy on-screen couple and they will be fun sparring partners as their dream destination wedding erupts into a memorable nightmare."

Duhamel, who has previously acted in the "Transformers" franchise and "Love, Simon," also stars in the upcoming Netflix superhero drama series "Jupiter's Legacy."

USA TODAY has reached out to Hammer's reps for comment.

Hammer, 34, was originally slated to star in the film, but confirmed his exit from the project on Jan. 13 after controversial Instagram messages he allegedly sent detailing sexual fantasies went viral.

"I’m not responding to these (expletive) claims but in light of the vicious and spurious online attacks against me, I cannot in good conscience now leave my children for four months to shoot a film in the Dominican Republic," Hammer said in a statement to USA TODAY at the time. "Lionsgate is supporting me in this and I’m grateful to them for that."

Hammer's alleged ex-girlfriend Courtney Vucekovich detailed her experience dating the actor in a Jan. 14 interview with Page Six. The publication reports the pair dated from June to August of last year.

Throughout their relationship, Vucekovich claimed that Hammer manipulated and abused her: "He kind of captivates you and while being charming he’s grooming you for these things that are darker and heavier and consuming. When I say consuming, I mean mentally, physically, emotionally, financially, just everything."

After the pair broke up, Vucekovich says she entered a 30-day partial hospitalization program geared toward PTSD and trauma. "As a strong mental health advocate I knew that this relationship was something I needed to process with help from people who specialize in trauma and PTSD. That is my experience," she told the outlet.

Later in January, another woman, Paige Lorenze, spoke  to Page Six with allegations. The outlet says she and Hammer dated for four months last year and that Lorenze is seeking therapy as she processes the psychological effects of their relationship.

“There were red flags throughout the relationship," she said. "I guess I just put them to the side and he made me feel so confident at times.”

Hammer's ex-wife Elizabeth Chambers addressed the allegations in an Instagram post Monday, writing that she's "shocked, heartbroken, and devastated."

"Heartbreak aside, I am listening, and will continue to listen and educate myself on these delicate matters," she added. "I didn’t realize how much I didn’t know.

I support any victim of assault or abuse and urge anyone who has experienced this pain to seek the help she or he needs to heal."

Chambers and Hammer have two kids: Harper, 6, and Ford, 4.

"Thank you for all of the love and support, and thank you in advance for your continued kindness, respect, and consideration for our children and me as we find ways to move forward," she wrote.
