The star said he had been unaware Nicol Harness had been sued for selling 18 drinks tumblers with his face on.
Ms Harness said she only learned of the legal action after the ruling, which came days after she was in hospital.
Combs said he called her to apologise and promised to send $11,000 (£8,600).
That’s double the $5,500 that was initially frozen in her account following the judge’s order, meaning she couldn’t pay her bills.
The 33-year-old Grammy-nominated singer has now started selling his own tumblers on his official merchandise store, with all proceeds going to Ms Harness.
