UK TV watchdog, Ofcom, is to investigate the performances of Rihanna and Christina Aguilera on last weekend's X Factor final.
The starlets wore skimpy costumes and gyrated provocatively, thrusting arses and boobs at the camera, prompting 2,750 complaints to the watchdog and 1,500 to ITV.
A spokesman said: "We are investigating the show to see if it was too strong for the time it was shown."
But a source close to the spokesman added: "There's more to it than that.
"The folks at Ofcom weren't watching the show and forgot to Sky Plus it, so they're getting hold of Rihanna's and Christina's people to arrange a reprise of the performances.
"They've decided to invite them to demonstrate the dances at the Ofcom Christmas party, which they're holding at a club in Soho on Thursday.
"Should be a good night!"
