Former American Idol runner-up Clay Aiken is a happy man.

Not only was he able to artificially inseminate Jaymes Foster and pass on his DNA to Parker Foster Aiken - born to his best friend and former produce in North Carolina August 8 - the singer will be reprising his Broadway role.

Expect Clay back in Monty Python's Spamalot next month!

Clay Aiken, 29, who performed the role of Sir Robin earlier this year from January-May, has signed on for a September 19-January 4 stint.

According to Variety, Clay Aiken’s initial run with Spamalot "had a noticeable effect on box office. Weekly sales surged the week that Aiken joined the cast and took a steep tumble shortly after he departed."

Really, who wouldn't pay to see scenes like the one shown here.

We just hope that Jaymes Foster, 50, who left the hospital Monday, and little Parker are able to catch a few of his performances.
