Once upon a time, Gwyneth Paltrow joined “Glee” to promote her upcoming movie and show the world she could sing — and this weekend, all that effort earned her an Emmy Award. Paltrow won the Guest Actress in a Comedy prize at this weekend’s Creative Arts Emmy Awards, a week before the primetime ceremony on Fox.

Other Creative Arts Emmy fun facts:

* Jeff Probst extended his winning streak to four years, grabbing the trophy for host of a reality or reality competition show. This comes even after he’s shared his disappointment last year at the category being moved out of the primetime awards. (Though after the reality show host-hosting disaster, who could blame the academy?)

* The controversial “Kennedys” miniseries, which was shockingly nominated for 10 Emmy awards after it was dumped by the History and picked up by ReelzChannel, picked up three trophies: makeup, hairstyling and sound editing for a miniseries.

* Silver Spring-based Discovery's “Deadliest Catch” snagged four trophies, including one for reality program. It tied for the second-most winning show of the evening, except for...

* “Boardwalk Empire,” which received seven awards (makeup, art direction, etc.), giving a good indication of how the heavily-nominated Prohibition-era drama should fare next Sunday.
