EC3 is Maverick's best man in the wedding, which was also mentioned on WWE TV during a RAW segment last week. EC3 and Drake have been friends since their time together in TNA. Braun Strowman is also a groomsman for the wedding.
Maverick's bachelor party was held at Big Daddy's in Orlando, Florida last night and as revealed in the photos below from Strowman.
Below are a few more shots Drake tweeted from wedding weekend, including a photo with Maxel, Matt Hardy's son.
There has been speculation on WWE filming a WWE 24/7 Title change at Drake's wedding, but nothing has been confirmed. Hardy and EC3 have been a part of some of the WWE 24/7 Title chase segments on RAW and SmackDown, and a wedding would fit the type of title changes WWE is trying to do with the new belt.
