Wha da?! Ariana Grande and SNL's Pete Davidson are ENGAGED after dating for 2.5 minutes! Both kids recent dumped their respective significant others and after just a few weeks of dating, they've decided to make a life commitment to each other, according to Us Weekly.

Grande and Davidson were reportedly spreading the happy news at Rob Pattinson's birthday party Saturday in LA. A source tells the mag: "They are a perfect fit. They are not rushing to get married. Their friends are really excited and supportive ... They are both constantly making each other laugh. Their moms have met. They’ve been very public with their relationship on social media, and they are very in love."

Davidson's already got two Ariana-inspired tats so it BETTER be for real!
