AceShowbiz - Amanda Seyfried's husband Thomas Sadoski had to wrestle with feelings of jealousy when his wife reunited with ex-love Dominic Cooper on the set of "Mamma Mia! Here We Go Again".

The actors met and fell in love both on and off screen during the making of the first film, and Amanda ended up dating Dominic, who plays her boyfriend in the movie and her ex in its sequel, from 2008 to 2010.

The 32-year-old is now married to "The Newsroom" actor Thomas, 42, but in an interview with British newspaper the Daily Mirror, she shared her husband still believes the British actor is in love with her.

"I think he has the same kind of issues that I would have if we were hanging out with his ex-girlfriend from long ago," the actress told the publication. "I think it's always like, 'I'm so in love with this person, so that person must be so in love with her too'."

"I assume everyone's in love with Tommy because I'm in love with him. I assume that everybody sees him the way I do," she continued. "I'd guess he assumed Dominic is in love with me the way he's in love with me. And it's just not the case.

"It's sweet. I'd rather he be jealous than completely fine with it. He's been great. He's very supportive and he loves this movie, and (he and Dominic) got along absolutely fine when we were shooting."

The pair star alongside Lily James, Meryl Streep, Christine Baranski, Cher, and Pierce Brosnan in the sequel to the 2008 box office hit which premieres on Monday night (July, 16).

Meanwhile Dominic, 40, also spoke about working with his real-life ex in an interview on British morning show "Lorraine".

"It was lovely. We stayed in contact," he told host Lorraine Kelly. "We've worked together so much in the past.

"With everyone in that cast, getting back together after that amount of time, the only way I could really think of what it must be like is like a school reunion... Whisked off to a beautiful part of Croatia, we just had a joyous (time), it was like a family."
