CELEBRITY BIRTHDAYS (4/4/11): Robert Downey Jr. - 46   To paraphrase Ozzy Osbourne, he is "Iron Man". And he's "Sherlock Holmes" too. 

Check out how buff he's gotten for the "Sherlock Holmes" movies ...  Humina, humina, humina!!!

--Craig T. Nelson - 67    These days he's the dad on NBC's "Parenthood"  but before that  he was "Coach".  He's also the voice of Mr. Incredible in "The Incredibles," and was the dad in "Poltergeist".  (RUN TO THE LIGHT, CAROL ANNE!) 

Ed O'Neill owes his role on "Modern Family" to him. Nelson was offered the role originally but turned it down because he found the money offered insulting.

--Amanda Righetti - 28   The HOT, and I do mean HOT, Grace Van Pelt on "The Mentalist". Man, I love red heads!!! ...

 --James Roday - 35   Shawn the "psychic" detective on "Psych" ...

--Nancy McKeon - 45   These days she's Connie Monroe on the Disney Channel's "Sonny with a Chance" but to your mom she'll always be Jo Polniazek on "The Facts of Life." 

All together now: ♪You take the good, you take the bad, you take them both and there you have the facts of life, the fact of life♪

--Estelle Harris - 79  George Costanza's mom on "Seinfeld" and Mrs. Potato Head in the "Toy Story" movies ...
