PewDiePie has amassed 37,145,260 subscribers and counting on his YouTube channel and has a variety of videos from silly and sometimes gross challenges to all things video games and more.

He recently teased on his Twitter Tuesday a photo of himself dressed up as an old man donning a really wild gray haired wig with a matching mustache. He also has a walking cane, glasses and a very stereotypical grandpa-like outfit.

"In 2 days the beginning of the new world arrives!" he dished.

On Wednesday he continued to tease his over 6 million Twitter followers with yet another photo. He traded in his grandpa style for something a teenaged girl would wear presently. He's rocking a black crop top and floral pants or perhaps a long skirt. PewDiePie also has a very blonde wig on, which is styled into braided pigtails.

PewDiePie really committed to this look since his nails are even polished! Plus, to really capture the essence of a young female, he's blowing a kiss to the camera.

He revealed that tomorrow, June 11, "Lives will change. Hairs will stand. Ovaries will burst open. Awkward liquids will flow."

We're uncertain of what he has in store for his fans, but he did pose the question, "Are you ready?"
