Don’t forget — the cast of Dancing With the Stars Season 18 will be revealed bright and early tomorrow morning (Tuesday, March 4) on Good Morning America. Be sure to come back to us as the news breaks and share all your thoughts with the class.

For now, we’re still in mystery mode, but the pros know who they have as partners. Karina Smirnoff shared a fun tease over the weekend, posting this black-and-white-photo on Instagram, writing, “Guess who?”

Hmmm. Maybe The Wicked Witch of the West and the house is just out of view? It’s someone with relatively skinny ankles but meatier calves. Could it be … Sean Avery? The NHL star is one of the rumored cast members for the spring season, and sleuthing fans noticed Sean just started following Karina on Instagram the other day. Coincidence?

All will be revealed (hopefully) when the new cast is announced tomorrow. Do you think Karina will be with Sean, or perhaps Cody Simpson, another rumored cast member? Neither? Whoever she gets, it’s hard to imagine he’ll be a better dancer than Corbin Bleu. Talk about big shoes to fill!

DWTS Season 18 premieres Monday, March 17 at 8 p.m. ET on ABC.
