Confidenti@l has officially been invited to Howard Sternâ€™s 60th birthday celebration, where weâ€™ll be bringing our readers all the nitty-gritty from the King of All Mediaâ€™s Jan. 31 Hammerstein Ballroom extravaganza. Stern has repeatedly groused on his Sirius XM radio show that deciding which A-listers to invite to the intimate 1,500-person party has been a struggle. Weâ€™re thrilled to have made the cut. Now, what do we get for the man who has everything?................. ............... â€œThe celebrity guest booking war has begun. As quiet as theyâ€™d like to keep it, thatâ€™s TV,â€ our source says. â€œBefore, celebrities doing press in L.A. did Leno, and stars in New York did Letterman. Publicists could blame travel budgets for booking one show over the other.â€ Thatâ€™s not the case anymore, says our insider, who says bookers for Letterman, 66, are revealing their displeasure about losing younger A-listers in Tinseltown. â€œItâ€™s likely the Jonah Hills, Bradley Coopers and Emma Stones in the game turn to Fallon now. Heâ€™s more of a friend to them.â€ Add to that Lettermanâ€™s old war with Leno and a policy of not booking the lame-duck â€œTonightâ€ hostâ€™s recent guests, and the formula leaves the CBS king with old loyal standbys like Julia Roberts, Meryl Streep and Howard Stern.
