This groom had quite a shock on his wedding day!

A groom was recently pranked by his best man during what was supposed to be the groom’s first look at his new bride

In a clip posted on TikTok, the best man -- wearing a white dress, a veil and no shoes and holding a bouquet -- walks up behind the groom and puts his hand on the groom’s shoulder.

The groom turns around slowly with his eyes closed, presumably in anticipation of seeing his soon-to-be wife.

However, when he opens his eyes, the groom is clearly shocked to see his best man instead, pretending to be his bride.
