And now, Pete is sure that she did it to sabotage his sex life.
In June last year, Ariana posted a (now-deleted) tweet saying that Pete was "like 10 inches", which is 25cm. Yah.
The post inspired the whole "big dick energy" thing that people became obsessed with, aka, BDE. At the time we're sure Pete was absolutely loving it, but now, he's not too happy about it.
"Everything is huge to her," Pete explained of Ariana, talking at a stand-up gig on Saturday night in New York.
"Why would she tell everyone that I have a huge penis? So that every girl who sees my dick for the rest of my life is disappointed," he explained.
Even after their break up, Ariana insinuated that Pete had one helluva shlong, in her music video for "Thank U, Next."
During the burn book scene, Ariana wrote "HUUUUGE" next to the photo of Pete.
Since the breakup, Pete has been rumoured to have a fling with 45-year-old actress Kate Beckingsale, who is 20 years older than him. Maybe, she was a little disappointed?
