The EDM producer and actress sparked romance rumors after being spotted out and about together over the weekend, and their PDA only fueled that fire.
A source tells E! News that the duo weren't hiding their feelings for each other on Saturday night after arriving together to a house party. "Calvin and Eiza were together the entire time. They were socializing with everyone at the party. They were holding hands and were very touchy-feely."
The insider added, "Calvin and Eiza were canoodling all night. It was obvious they were totally into each other."
However, despite their outward affection towards each other, E! News learns that this isn't a new couple alert—Calvin is just having fun and enjoying the single life following his public breakup with Taylor Swift.
