Talk about speed dating! In just over a month, Ariana Grande and Pete Davidson have gone from flirting to dating to getting engaged. But this whirlwind romance could come at a cost — to Ariana. As the couple plan a wedding, "Ariana’s family is urging her to pump the brakes and slow down long enough for Pete to sign a prenup," an insider exclusively tells Life & Style.

"She has much more money than he does, but all she can think about is getting married." The "No Tears Left to Cry" singer, 25, is worth about $45 million, while the Saturday Night Live star is worth close to $2M. "No one is saying Pete is a gold digger," the insider notes, "but if she isn’t careful, she could lose a lot."

When it comes to Pete, 24, Ariana isn’t interested in being careful. "She’s not listening to anyone," says the insider. Adding on, they "are freaking out" about how fast she's moving. "She says she knows in her soul that she and Pete will be together forever. But that’s exactly why her parents are worried — she barely knows Pete!"
