Ryan Garcia says his marriage to Drea Celina was beyond repair -- the boxing star filed for divorce due to "irreconcilable differences" ... this according to court docs obtained by TMZ Sports.
As we previously reported, the 25-year-old pugilist announced his split from his wife of nearly 3 years via his Instagram account Friday night ... just minutes after revealing they welcomed their second child together.
In the docs filed last week, Garcia says he and Celina -- who got married on Jan. 14, 2021 -- were officially separated on Christmas Day 2023.
The 24-1 fighter says he is willing to financially support their two children -- 3-year-old Bela and Henry, who was born last month -- based on the minor children's "reasonable needs."
As for Drea, the docs state Garcia is open to paying spousal support to her for the next 17 1/2 months -- half the time they were married.
In the divorce announcement, Garcia said co-parenting is the former couple's "top priority" ... and he will continue to focus on Bela and Henry's health and well-being.
