Debi Mazar s Dancing With the Stars debut is still three weeks out, but the actress has already won a pretty nifty prize from ABC: a recurring stint on Castle.

Sources confirm to me exclusively that Mazar is joining the second-year dramedy as Paula Haas, book agent to Nathan Fillion s modern-day Jessica Fletcher.

She ll first appear in October when she makes Castle an offer he ll find hard to refuse.

Accepting said offer, however, would cause a fair amount of upheaval in his life, particularly his relationship with Detective Beckett.
