Clay Aiken's baby mama has popped!

Aiken's mother told local Raleigh, N.C. TV station that the "American Idol" runner-up was now the proud papa of a bouncing baby boy named Parker Foster Aiken.

Aiken's BFF, 50-year-old record producer Jaymes Foster, gave birth at 8:08 AM this morning in an "undisclosed location." TMZ was the first to tell you he had inseminated Foster.

Aiken's mother Faye said the dark-haired Parker weighed in at 6 lbs. 2 oz and was 19" long. She says her son is "smiling from ear-to-ear."

Mom, dad and baby all are doing fine, according to Faye.

Aiken and Foster, who met when Clay appeared on "A.I.," will raise their spawn together.
