Ariana Grande Covers Up Pete Davidson Tattoo with Band-Aid

Ariana Grande is making an attempt to cover up any and all signs of Pete Davidson ... even if it means hiding a tattoo dedicated to Pete with a Band-Aid.

Grande performed "The Wizard and I" Tuesday in NYC during a pre-taped segment for the upcoming NBC special dedicated to the Broadway musical, "Wicked." Ariana has a "pete" tattoo on her ring finger, and you can see in this side-by-side, she made sure to cover it up for any close-ups.

The special is set to air October 29, meaning the split will be more than two weeks old ... so hiding the tattoo now does make a lot of sense.

TMZ broke the story, the "Wicked" performance was Grande's first public appearance since the split ... Davidson was set to headline a comedy gig at Temple University Wednesday, but dropped out last minute.

In a post that's apparently since been deleted, Ariana said, "time to say bye bye again to the internew for jus a lil bit. it's hard not to bump news n stuff that i'm not tryna see rn. it's very sad and we're all tryin very hard to keep goin. love u. and thank u for bein here always."

Ariana's also parted with the $100k engagement ring from Davidson, but will keep the couple's teacup pig.
