'Shear Genius' Star -- Marriage Comes to a Split End

Hair god Jonathan Antin -- a judge on Bravo's hair-styling show "Shear Genius" -- has gotten the chop from his wife ... who just filed for divorce.

TMZ has obtained the divorce papers filed by Jonathan's wife, Sescie Antin -- whom Jonathan married back in 2006.

According to docs, Sescie cites irreconcilable differences for the split.

The couple has 2 children together -- a 5-year-old and a 4-year-old. Sescie has requested joint legal custody -- but she wants primary physical custody, with Jonathan getting visitation rights.

Sescie also claims she and Jonathan have a prenup -- which states that he will cover her mortgage and all home expenses until their youngest child is 21 -years-old.
