Anthony Kiedis' barely legal girlfriend looks ready to pop!

TMZ spotted the 44-year-old Red Hot Chili Pepper "singer" out with his decades younger and incredibly pregnant girlfriend, 21-year-old model Heather Christie.

This will be the couple's first child -- and so far, they have no plans to "give it away."
