The pair co-starred in the 1998 romantic drama, and are set to have an entertaining chat on the first episode of the former American Idol judge's long-awaited series, which premieres on 12 September (16).

Amy Adams, Renee Zellweger and Empire star Terrence Howard will also make appearances in the premiere week, while Kristen Bell, Zooey Deschanel, Russell Crowe, John Stamos, Anthony Anderson and Taraji P. Henson are also slated to join Harry.

Speaking recently about his chat show, Harry admitted he feels honoured to have been given the opportunity to front such a diverse programme.

"I couldn't be more excited," he told "I really feel like I’ve won the lottery - just to be able to show up every day and meet and talk to interesting people and play music and do it all under one roof in an unstructured, spontaneous way, it’s really fun."

Harry will give the 48-year-old a chance to showcase his musical skills and his electric personality. But the thing he loves most about the series is its spontaneity.

"There’ll be a piano right there (on stage) - some days I might play and some days I won’t," he explained. "The fun thing about it is that we’re going to read each audience and see what happens. Sometimes you might call for a tender romantic song, or no song at all, or crazy New Orleans music - it could be anything really."

In a previous chat with WENN, Harry also revealed that he has noted all the things he hates on other people's chat shows - such as pre-interviews and awkward games - and ensured they are cut from his programme.

"I hate the pre-interviews and I would tell them (crew members), 'Do we have to do them?' and they said I had to do them," he told WENN. "I want to be the type of host that wants to learn about you today, in the moment. It's my job to know everything about that person. I think of it like, 'What are we gonna talk about?'"
