And they certainly looked cozy as they were snapped leaving a party together in matching black outfits.
Inside the bash, the duo was “canoodling all night,” according to an E! News source.
"Calvin and Eiza were together the entire time,” says the insider. “They were socializing with everyone at the party. They were holding hands and were very touchy-feely. It was obvious they were totally into each other."
Gonzalez previously made headlines after being spotting making out with Liam Hemsworth one day after reps confirmed his split from Miley Cyrus in 2013.
The 26-year-old actress and singer has also been previously linked with soccer star Cristiano Ronaldo.
Meanwhile, Harris (real name Adam Wiles) has been linked with singer Tinashe and is said to simply be enjoying the single life.
“Adam is entertaining a few different women and having fun!” another source tells E! News. “He is not taking anything too seriously. He is still hanging out with Tinashe and is talking to Eiza. Seems like she is a sweet girl, he said. They are just chillin'. Adam is getting back in a better place in his life. He is not looking for a relationship at all."
