Bridezilla, Never Provoke The Billionaire Mother

A mother comes back from abroad for her son's wedding. The bride takes her for his mistress and accuses him of cheating, then joins her own family and the bridesmaids in bullying her. The groom arrives and the truth comes out, and they realize the woman is his mother. To get her son to call the wedding off, she lays out the bride's real motives for the marriage. One phone call from her could bankrupt the bride's family, so the family and friends turn their backs on the bride one by one. The bride's own infidelity is then exposed in public. The groom sees what she is and cancels the wedding, and she loses everything and is handed over to the law.
