Pamela Anderson and Liam Neeson raised quite a few eyebrows as they promoted their new The Naked Gun reboot, as onlookers wondered if their affection for each other was real or just for show .

Leslie Nielsen first appeared as bumbling detective Frank Drebin in parody series Police Squad, before reprising his role in the first three Naked Gun movies – between 1988 – 1994. In the reboot, which serves as the fourth film in the franchise, Liam appeared as his son, Frank Drebin Jr.

The outlet's source also noted that the 58-year-old actress and her actor beau were "learning how to navigate" their newfound romance together. "They are both shy and have tried to stay private but the spark between them is obvious," the insider said.
