AceShowbiz - Olivia Rodrigo and Adam Faze's romance is heating up. During an out and about in Los Angeles, the "Drivers License" hitmaker and her boyfriend were caught on camera enjoying a steamy makeout session.

On Sunday, November 28, the 18-year-old singer and the Hollywood producer were photographed jumping out of a black Range Rover Sport. Before leaving the car, the twosome shared a passionate kiss as he wrapped his arms around the musician.

For the outing, Olivia kept casual in a black tank top, army green cropped pants and black-and-white sneakers. Her beau, on the other hand, looked simple in an all-black ensemble.

This was not the first time Olivia and Adam were spotted packing on the PDA. In July, the twosome was seen holding onto each other as they leaned on an Audi during a date in Los Angeles. At one point, the "Deja Vu" songstress payfully pinned her boyfriend on the car before she gave him a smooch.

The Grammy nominee later adoringly placed her hands on Adam's face and snuck her hands under his T-shirt as she smiled. Another snap showed the pair lovingly hugging each other.

Olivia and Adam first sparked romance rumors in June. At that time, they attended the premiere party for "Space Jam: A New Legacy" together at Six Flags Magic Mountain in California. An eyewitness reported that the two were indeed an item as they were holding hands throughout the evening.

One source additionally claimed that the duo has been dating for "a few months." The source further explained, "She seems really happy with him and they are definitely dating exclusively and getting serious."

Before dating Adam, Olivia was linked to Joshua Bassett. Following the release of her hit "Drivers License", many assumed that her "High School Musical: The Musical: The Series" co-star broke up with her just to date Sabrina Carpenter.
