Pete Davidson made a dirty joke about Ariana Grande when a fan quizzed him on what life with his fiance popstar is really like.

The Saturday Night Live comedian popped the question to Ariana in June (18), weeks after the couple went public with their new romance.

Performing at Auburn University in Alabama on Thursday (August 23, 2018), Pete was probed on what effect the proposal has had on the couple’s relationship – and the funnyman didn’t hold back.

“What’s it like being engaged to Ariana? It’s like what you would think it was like but, like, 100 times sicker. It’s f**king lit,” the 24-year-old told the cheering crowd. “I’m a very, very lucky boy, and I’m very, very loved and I’m very lucky.”

He then added: “And my d**k’s forever hard.”

While some fans were shocked by his cheeky response, Ariana, who was backstage at the event, appeared amused by her fiance’s comments and took to social media to congratulate Pete on his set.

“Bae was funny as f**k and brilliant today as always,” she gushed on her Instagram Stories alongside a black-and-white photo of herself sat on Pete’s lap.

The following day, the Side to Side songstress was forced to defend her husband-to-be once again after an article entitled ‘Does Pete Davidson Have Butthole Eyes?’ appeared, mocking his tired appearance.

“y’all do kno this man has an auto immune disease …… right ? ….. like you do understand what you’re doing when u do this right ? jus wanna make sure (sic),” she questioned on Twitter, referencing Pete’s battle with inflammatory bowel disease Crohn’s, which is known make the eye area become swollen.
