The "Hands To Myself" hitmaker has been rumoured to be dating the "Starboy" rapper since the pair were spotted locking lips earlier this month.
Gomez has proved things are heating up between them by clicking the follow button on his profile on the photo-sharing app, as she only follows 256 people, reported Us magazine.
Gomez's cousin and close family friend Priscilla DeLeon is also following the Grammy winner, whose real name is Abel Tesfaye.
"He really likes her. They text every day. They have a really sexy and flirty relationship. They laugh and like each other's personalities," a source said about the budding relationship.
