Entertainment Tonight has a secret party plan.

For the past few years, the ET Emmy party has been held at the Mondrian on Sunset. But the ongoing problem has been that the party gets packed early with people not attending -- or not invited to -- the awards show. They all come to watch the show on big plasma screens. And they stay aaaall night long.

So when Emmy nominees and winners arrive after the show, there's no room! There are countless stories of stars asked to cool their heels outside the bash until there was room to squeeze them in. Ouch. Never tell a star holding an Emmy to wait outside a party. Especially on a night with several competing parties eager to welcome them.

And let's not even mention the nightmare of the Mondrian's valet debacle.

This year, the ET bash will be held  -- ta-da! -- downtown at the Walt Disney Concert Hall.  This may: A) keep away some guests who don't want to trek downtown to watch the show, and B) tempt A-listers to do a drive-by after their prerequisite pitstop at the Emmys' Governor's Ball at the nearby Shrine.

This plan could backfire. It all depends on who wins what and where all the other parties are held. It's a straight shot down Beverly to Robertson to the site of HBO's fete, always THE party of the night, traditionally held in a huge tent outside the Pacific Design Center at the corner of Melrose and Robertson.  No word from HBO about a change of venue.

No confirmed talent for the ET party, either. But an inside source says Mary J. Blige, Bon Jovi and Barry Manilow are on the possible performer list. I vote for Bon Jovi. Anybody else?
