A TikTok user captured the moment a woman crashed a wedding ceremony in Detroit, Michigan and shocked guests as she announced herself as the mother of the groom’s child.

Footage of the incident has gone viral on TikTok since the chaos unfolded yesterday when the pregnant woman turned up at the outdoor wedding.

In the 33-second clip, a marriage officiant is reading the vows to the couple at the dome-shaped patio when a woman yells from behind.

She is heard saying: “Anthony! You pretend you didn’t know me? didn’t get your psych med today?

“Anthony I know you hear me! You’re acting like you don’t know me…I got your baby here!

A few guests murmur behind the camera and whisper: “Oh no. Oh my God!”

The bride and groom look unfazed as the officiant carries on with the ceremony.

At one point, a young woman, who is seen holding a bouquet in her hands, dashes out of the patio.

She throws the flowers at the woman and shouts: “You better get out of my mama’s wedding.

“What is wrong with you? What is wrong with you?”

The bride and groom turn around before the video ends.
