"YOU WILL do foolish things, but do them with enthusiasm," said Collette.

It is difficult to equate the brilliant actress Jennifer Lawrence and her big movie hit "The Hunger Games: Catching Fire" with the silly promotion "The Late Show with David Letterman" gave her the other night where she behaved as if she were nuts. Maybe winning the Oscar and extreme success is nerve wracking. Letterman doesn't help when celebs go astray -- the sillier the better for him; he has nothing to lose.

A lot of TV these days looks like accidents about to happen. I guess that's the point.

The excellent Manhattan Theatre Club is offering another play with a meaningless title that you can't remember when people ask what you've seen. "The Commons of Pensacola" is actress Amanda Peet's debut as playwright and it is slight and mercifully short.

But it boasts two popular names, good actress Blythe Danner and the dedicated star Sarah Jessica Parker, along with a neat cast. (I especially liked Nilaja Sun as the sensible maid.)

If you want disheveled glamour masquerading, then the glorious Ms. Danner and the super famous Sarah Jessica Parker are here looking mostly terrible. Ms. Parker deserves an A plus for acting in unattractive attire showing she is a real drama queen. Even the most failed actress wouldn't be seen in such dreck.

The play about a Madoff-type comedown is so slight it becomes almost invisible as the actors struggle with the same dialogue over and over.

This "try," directed by Lynne Meadow, is more of a curiosity than anything else. But when you can get Blythe Danner and Sarah Jessica Parker onstage, It doesn't matter. I love them both and they are real theater pros.

The Times liked this play, even with its forgettable title. You always have to give the Manhattan Theatre Club a break for all the good it does in the theater.

FRED ASTAIRE is best known for his magnificent, effortless dancing. But a lot of people don't realize he had a charming, evocative (if light) singing voice. In fact, his contributions to the musical film as a singer are invaluable, his voice unmistakable.

Fred introduced and popularized such classics as "Night and Day," "Cheek to Cheek," "Top Hat, White Tie and Tails," "A Fine Romance," "A Foggy Day," "They Can't Take That Away from Me" and dozens of others.

Now Sony Mastersworks (http://www.sonymasterworks.com), in conjunction with Turner Classic Movies, will release a new two-CD set; "Fred Astaire: The Early Years at RKO." This is available now. (Fred will be Turner Classic Movies' "Star of the Month" in December.)

I LOVE THAT such a big deal was made about Justin Bieber recently requiring guests at his raucous party in L.A. to sign $3 million dollar "confidentiality" agreements. Who doesn't do that, these days?

Tom Cruise's wives are, allegedly, "asked" to sign up. It's really not a bad idea. It protects the celebrity, and it even protects guests and wives and others who toil for the celeb. The tattle-tale never comes out of it looking good, they are always the victim of those infamous two words -- "disgruntled ex-employee" or "scorned wife."

Everyone who knows me, knows that I am enamored by Le Veau d'Or, an old-fashioned French bistro between Lexington and Park on East 60th Street. This cafe has been thriving in Manhattan since the '30s and has been owned by only two families.

Now it operates at the whim of the beautiful and charming last family's daughter, Cathy Treboux. It's almost like a private club, but if you behave yourself, Cathy will take you to her heart and feed you very well. And the Veau is a place where you can talk and hear yourself think.

This cafe had its heyday during the era of "the lates" -- Vogue's Diana Vreeland, Jackie Onassis, Truman Capote, before he blew himself up socially, and others of literary, food and social fame. Not long ago, the Veau won the James Beard Award as the best French bistro in the United States and Cathy's father (now gone to his reward) exclaimed upon winning: "It's all bull-sheet!"

YOUNG Robert Summerlin, M. Treboux's grandchild, has lately been making waves in Paris.

If you happen to go to the Great Canadian Sports Pub on the Left Bank, you can ask for him. He is very attractive, speaks English and French and can discuss international sports until the cows come home. Customers love him and go there to keep up with soccer and everything else.
