Pamela Anderson has hailed Liam Neeson for putting her at ease during the filming of The Naked Gun reboot.

The former Baywatch actress, 58, has been widely reported to be in a relationship with Schindler's List star Liam, 73, and she has now spoken to the New York Times to praise her co-star him for helping ease her nerves as they shot the cop comedy reboot.

She said: "He has so much charm and so much charisma that you kind of just fall into it.

"I can't explain it because I've never experienced it before."

The new Naked Gun film marks a reboot of the classic American crime spoof franchise originally made famous by Leslie Nielsen.

Liam takes on the lead role as detective Frank Drebin Jr., while Pamela plays his love interest, Beth -- a woman convinced her brother has been murdered, launching the pair on an absurd adventure across Los Angeles.

Pamela added she "still felt unsure of herself at times during filming", but said Liam's calm presence on set kept her grounded.

She said he told her "You're doing great" during shooting.

Pamela added: "To do comedy, it gives you a lot of energy when you're in something so joyful and silly. "Liam has done over 100 movies, and I hope he's inspired to do even more (comedies.)"

Liam, known for dramatic and action-heavy roles in the likes of Taken and Batman Begins, also admitted to having doubts about leading a comedy.

He told the New York Times: "I don't think of myself as funny-funny, but I love laughing and gagging about."

Reflecting on his performance, he added: "I thought I was OK, seriously. I thought I was OK."

The Naked Gun franchise began in 1982 with the TV series Police Squad! and expanded into three successful films.

A source close to the production has told People Pamela and Liam are "in the early stages" of a relationship, calling it "a budding romance".

The insider added: "It's sincere, and it's clear they're smitten with each other."

Pamela and Liam pair are currently promoting the film and, according to the source, are "enjoying each other's company" off-screen during the promotional tour.
