Sean Combs, a.k.a. “P.Diddy,” agreed to pony up more than $4.5 million in child support for his youngest son, Christian, 3, the “New York Post” reported. The hip-hop star and the child’s mother, model Kim Porter, reportedly reached a settlement on their own, and Porter and lawyers for both sides appeared in family court in New York Wednesday to make it official. Though terms of the settlement were not disclosed, the “Post” reported that Porter will receive a lump sum of $150,000, plus $20,000 per month until Christian turns 21. In addition, Combs, 32, will pay for Christian’s college and insurance costs as well as Porter’s legal fees. Combs also took out a $2 million life insurance policy, to which Christian is beneficiary, the “Post” reported.
