Singer Clay Aiken

Proud poppa Clay Aiken can't get enough of Broadway.

The "American Idol" alum, who recently became a father, will return in September to the New York company of "Monty Python's Spamalot," where he again will play the role of Sir Robin.

Aiken will be in the musical, based on the film "Monty Python and the Holy Grail," Sept. 19-Jan. 4.

On Aug. 8, Aiken announced the birth of his son, Parker Foster Aiken, on his Web site's blog. "No hyphens. One first name," he wrote. "One middle name. One last name."

The baby's mother is Jaymes Foster, Aiken's friend and record producer whom he met while performing on "American Idol."
