RadarOnline.com exclusively learned Grande, 25, has "blocked" Davidson, 24, after the SNL comedian refused let her go.
"She had to tell him straight up to leave her alone. He has tried contacting her and sending her gifts in hopes that she will change her mind and take him back, but that is not going to happen," a friend of Grande's said.
Amid her busy schedule, the singer was eager to let bygones be bygones. "Ariana is far too busy to focus on her past relationships and she has learned a great lesson from this, which is that she cannot give her heart away so easily," said the informant.
As Radar previously reported exclusively, following their split — which was triggered by the tragic overdose death of Grande's ex, Mac Miller — Grande booted Davidson from her swanky $16 million condo in Manhattan and changed the locks to keep him out!
In addition, the pop star returned her engagement ring, as well Davidson's late father's 9/11 dog tag necklace. She has already covered up the two tattoos she got during their brief relationship.
"When she is done with something she is done with it and Ariana is now focusing on her career and family," the pal told Radar, adding that her entire family is "relieved" that Davidson is dunzo!
"She had no idea how much everyone in her family didn't like him until she broke it off and was like 'why didn't you all tell me when we were together?' But ultimately they just wanted to see her happy."
