The 32-year-old looked comfortable with model Alexander Kjellevik as they shot scenes together as a couple, reports entertainmentwise.com.
The two were seen getting up, close and personal as he put his hands on her waist and rested his head on her hair while they were also spotted engrossed in conversation and laughing around on the roof of a non-operational petrol station.
Other photos taken during the day on set show Spears happily wrapping her arms around Kjellevik's neck before kissing him.
"Perfume" is set to release Nov 29.
