According to the L.A. Times, Swift and Alwyn were spotted "chowing down on burgers" at the VF party "sans any security."
The couple also attended Fox's Oscars after-party, which was held at the Hollywood Athletic Club.
Variety reports that Swift "kept a low profile" at the celebration as she and Alwyn chatted with his co-star, Nicholas Hoult. But, the outlet adds, the "biggest moment of the night" occurred when the couple left the party.
"Because before she made her way out of the party, she was so low-key in a private corner of the soiree, barely anyone even noticed she was there," according to Variety.
In a video posted to social media, Alwyn and Swift can be seen showing some PDA as they stand alongside each other at an after-party.
Before heading out to the parties, Swift shared a photo of herself sitting on stairs in a gorgeous Ralph & Russo dress. She captioned the social media photo with a heart.
