Sandra "Pepa" Denton gave her former groupmate DJ Spinderella the shock of a lifetime at her annual Halloween party -- but in a good way!!!

We got the proof ... on Sunday, Pepa crashed Spinderella's annual Halloween Boo Bash and stuck around to perform their classic cuts "Push It," "Shoop" and "Whatta Man"!!!

Pepa played the cowgirl and Spinderella was dressed as the Beetlejuice ghost host with the most when she hopped out the DJ booth to perform her "Whatta Man" verse.

Cleveland Browns superstar Myles Garrett's Halloween costume got the ultimate compliment on Sunday ... with none other than Arnold Schwarzenegger praising his Terminator outfit!!

The All-Pro defensive end was unrecognizable prior to the Orange and Brown's divisional matchup with the Baltimore Ravens on Sunday ... wearing an elaborate mask, leather jacket and sunglasses as he made his way to the locker room.

The team's social media accounts shared footage of the epic entrance ... and it made its way to the Terminator himself, who was clearly thrilled with the end result.

It's the time of year where even Hollywood A-listers wanna be someone else -- with many of them throwing on makeup and donning costumes for Halloween week!

With Halloween on Thursday this year, many celebs decided to dress in their scariest, silliest and sexiest costumes this weekend ... like Selena Gomez and Benny Blanco, who went down the rabbit hole with their "Alice in Wonderland" costumes.

Nearly three decades after Wes Craven's 1996 release of "Scream" -- the horror film surrounding a group of Woodsboro High School students, plagued by a harrowing serial killer -- is still a top scary movie amongst many generations.

A few of the breakout stars include Skeet Ulrich as Billy, Neve Campbell as Sidney, Matthew Lillard as Stu, Rose McGowan as Tatum and Jamie Kennedy as Randy.

It all began with Drew Barrymore's infamous over-cooked popcorn scene and a haunting phone call that ended with a "scream" that came a squeak too late ... And, of course accompanied by some eerily creepy, suspenseful music.
