According to RadarOnline, Ariana's mum, Joan Grande, and her brother, Frankie Grande, are "terrified" of how fast things have moved between the couple.
"Of course everyone is happy for her," the publication reports, "but they are also super worried that she is going to get her heart ripped out. Everyone thinks that he is using her. But she is not listening to anyone and is shutting out anyone who tries to wish her anything but happiness and joy."
The site also reports that Frankie is worried about his daily use of marijuana. "The red flags are everywhere and Ariana refuses to see any of it. Ariana’s brother, Frankie, is sober for over a year and he cannot believe that Pete thinks that smoking weed every day is okay after struggling with addiction. He has told Ariana this and she doesn’t want to hear any of it… She is in love and is convinced he is her soul partner. Nothing can change her mind."
