Calvin Harris may be crushing on Demi Lovato. Eagle-eyed fans noticed that the "This Is What You Came for" hitmaker liked a cleavage-baring snap shared by the "Cool for the Summer" songstress on Instagram on Wednesday, April 19.

In the photo, Demi looked smoldering hot as she flaunted her cleavage in a plunging, one-piece bathing suit. The "Body Say" singer wore round sunglasses, orange lipstick and her hair was tied in a ponytail.

What's even more interesting about this, though, is Demi's history with Calvin's ex-girlfriend Taylor Swift. Last year, the "Let It Go" singer publicly shaded the "Bad Blood" hitmaker on social media for donating money to Ke$ha, who was battling her producer Dr. Luke, rather than speaking out about the situation.

Demi is currently dating MMA fighter Guilherme Vasconcelos, while Calvin has been romantically linked to some women, including Jennnifer Lopez, Halsey and Tinashe, following his split from Taylor.
