Pete Davidson Returns to Instagram With Eli Manning, 'Stay Tuned'

Pete Davidson is back on Instagram, but there's a catch ... it's a joint page with Eli Manning!!

Yes, the former Giants star quarterback and comedian joined forces to launch the IG page together ... debuting the account Wednesday night with an IG video in Davidson's apartment.

"Hello Instagram," Davidson said on his Giants-themed bed, "I have decided to come back, but only with the GOAT."

"Stay tuned for more photos on the gram!"

The duo shared a video and a couple of photos, including a pic of Davidson's small helmet tattoo. Eli captioned the post, "confirmed ... Pete's a Giants fan."

The guys also worked on one-handed catches (a la Eli to Odell Beckham Jr. vs. the Dallas Cowboys) ... and Davidson has hands!

Fans loved the idea of the joint account ... they flooded their comments with support, with one saying, "lmfao the link up I never knew I needed 🐐".

FYI, Pete -- who's been MIA from IG since 2018 (he occasionally returns before deactivating again)  -- and Eli already have over 17k followers, as of Thursday morning.
