Wedding bells are (finally) ringing on Glee when Will (Matthew Morrison) and Emma (Jayma Mays) tie the knot on the Valentine's Day episode. And you better believe Mr. Schue's old students will be back to help him celebrate his big day.

Besides the one super awkward reunion we already know is happening, new photos show that Quinn (Dianna Agron) and Santana (Naya Rivera) will also be on hand for the occasion. But breathe easy fans: The two ex-Cheerios have put their Thanksgiving slapfest behind them.

"They sort of just brush that off which I thought was so funny and regular Glee fashion," says Rivera, who revealed both slaps were indeed real. (Here's hoping that truce lasts.)

Glee airs Thursdays at 9/8c on Fox.
