Source Confirms Liam Neeson and Pamela Anderson Romance

The pair, who co-star as onscreen lovers in their new action-comedy, have fueled dating rumors with their PDA-packed red carpet appearances while promoting the film.

Liam Neeson and Pamela Anderson have reportedly taken their onscreen romance into the real world. The 73-year-old actor and 53-year-old actress recently starred in "The Naked Gun," which releases in theaters this Friday, August 1.

The duo has been promoting the anticipated film in recent weeks, beginning with its London premiere on Tuesday, July 22. They walked the red carpet together for the first time, where they were captured sharing a sweet moment.

In circulating photos, Anderson can be seen planting a kiss on Neeson's face, who happily bows to accept it, his hand resting firmly on her back. The moment, and a few others that have since ensued, have fueled dating rumors between them.

Now, a source has come forward, confirming that the two are indeed in a relationship. "It's a budding romance in the early stages. It's sincere, and it's clear they're smitten with each other," the source told PEOPLE, adding that the pair are "enjoying each other's company."

Following the London and Europe premieres, Anderson and Neeson returned to the States for the New York first screening of "The Naked Gun." This time, they shared the red carpet with their sons.

Anderson brought her boys, Dylan and Brandon Lee, from her marriage to ex-husband Tommy Lee, while Neeson was accompanied by his sons, Daniel and Micheál Neeson, from his marriage to the late Natasha Richardson.

The following morning, Anderson and Neeson shared a funny moment on the "Today" show, where they pretended to be caught making out on camera. When asked about the footage and the status of their relationship, the two played coy.
