Rikki Rockett's divorce is officially over ... and it seems everyone is finally satisfied.
The Poison drummer and his ex, Melanie, will share joint custody of their 2 kids -- 7-year-old Jude and 4-year-old Lucy. Rikki will pay $2,000 a month in child support until the kids turn 18 ... and he'll also cover their club activities -- karate, tennis, swimming, etc. Melanie gets $1,000 per month in spousal support for 3 years.
Everything pretty much went according to their prenup, with one twist -- if Rikki's on a "full scale" tour with Poison ... his child and spousal support payments double in those months.
Rikki also has to pay off a Dodge Charger for Melanie and fork over $45k from the sale of one of their properties.
