According to People, Austin has had a thing for Fifth Harmony's Camila Cabello since seeing her at the MTV VMAs.
"Austin caught Camila's eye when they were both in New York for the MTV VMAs [in August]," a friend of the teens told the mag.
"They met the day before at the Arthur Ashe Kids Day and have been in touch ever since."
Back in December Austin Tweeted his support for the 16-year-old singer whose group finished third on season two of The X Factor.
"Hey gorgeous! Good job tonight. I voted for you," he tweeted.
"Austin thinks she is so cute and she feels the same," the source added.
"They're staying in touch and are looking forward to hanging out together soon."
We think Austin's tweet Sunday night was about Camila! He posted, "When I text you, it's because I miss you. When I don't text you, it's because I'm waiting for you to miss me!"
Do you think Austin and Camila are more than just friends?
