IF NANCY GRACE could dance with her mouth, she'd be an odds-on favorite to take home the mirrorball trophy on the fall season's "Dancing With the Stars."

Now that TMZ.com has reported Nancy's involvement, however, we're going to see if she actually has, dare we say it . . . grace.

Sure, she's tangoed with opposing counsel, but is she ready to do so with Carrie Ann, Len and Bruno? What happens if another tragic case raises Nancy's Shrill Level to Red? Will she able to calm her anger for a waltz?

We just want to see her dance with reported contestant Chaz Bono - and fight him to lead.

Michael Jackson update

The already questionable Michael Jackson tribute concert became even more questionable yesterday when sister Janet said that she would not be attending because the show coincides with the trial of Conrad Murray, the doctor charged in MJ's death.

Janet's one-sentence statement to the Associated Press does not criticize the show - she'll leave that to brothers Jermaine and Randy - but cites the court case as her reason for not attending.

"Because of the trial, the timing of this tribute to our brother would be too difficult for me," her statement reads.

Her statement was released on what would have been her brother's 53rd birthday.

Organizers of "Michael Forever - The Tribute Concert" have struggled to line up top-name acts and have been criticized by fans and the late singer's estate for multiple reasons, including its costly tickets and remote location.

Not to mention the exquisite bad taste of scheduling the show during Murray's trial.

The show is slated for Oct. 8 in Cardiff, Wales, and Michael's mother, Katherine, and some of her children are scheduled to attend.

Christina Aguilera, Smokey Robinson and Cee Lo Green are the top names listed as performers so far - but Tattle will not be holding our breath waiting for any of them to sing.

* In additional MJ news, his children and father visited his boyhood home in Gary, Ind., as the town celebrated his birthday.

Hundreds of fans took part in activities outside the house on Jackson Street.

Paris Jackson, 13, told WLS-TV that she enjoyed seeing so many fans at the house when she and her brothers, Prince, 14, and Blanket, 9, visited on Saturday.

The Post-Tribune of Merrillville reported that Michael's father, Joe, attended activities at the home on Sunday.

Hide the silverware.


* Sarah McLachlan ("I Will Remember You," "Building a Mystery") will perform at a dedication ceremony for the 9/11 memorial for Flight 93 in western Pennsylvania.

The National Park Foundation announced yesterday that Sarah will sing at the Sept. 10 event near Shanksville, where the 40 passengers and crew aboard United's Flight 93 died Sept. 11, 2001. The plane crashed in a field after it's believed that the passengers tried to overpower the hijackers.

The Flight 93 National Memorial dedication will include dignitaries and the relatives of those killed in the attack. A "Tower of Voices" memorial is designed to house 40 wind chimes. Organizers have raised most of the estimated $60 million needed for it.

* Word from the MTV VMAs is that Jo Calderone (a/k/a/ Lady Gaga) never broke character the entire night and even used the men's bathroom.

Using the urinal, however, remained a bit of a problem.

Tattle didn't get the whole Calderone thing - Is it music? Performance art? Both? - and we suggest that since Gaga got the great Brian May, of Queen, to riff with her on "You & I," she should have come out and performed as Freddie Mercury.
