The girl, who Entertainment Tonight reports is 18-year-old model Lindsay Vrckovnik, just graduated high school and is now studying at Parsons School of Design in New York City.
The pair was first spotted spending time together in New York last week, where they party-hopped on Wednesday night and didn't arrive back at Scott's hotel until 6 a.m. on Thursday morning. They were also spotted at 1 Oak nightclub, where a source inside the club told ET that they were looking pretty cozy.
"Scott was hanging with this girl all night," their source spilled. "He had his arm around her and they looked very couple-y. He kissed her a few times and was whispering in her ear with a smile on his face. She seemed very into him, but a little out of place, very uncomfortable when people were looking at her."
Despite their 14 year age gap, Scott and Lindsay seem to be getting along pretty well. They even jetted off to Miami over the weekend, where they were spotted soaking up the sun on a beach in Miami.
