Catherine Zeta-Jones has reportedly entered a mental health treatment center for a bipolar disorder ... despite her rep squarely denying the story to TMZ.

One of Catherine's reps now tells People.com, "After dealing with the stress of the past year, Catherine made the decision to check in to a mental health facility for a brief stay to treat her Bipolar Disorder."
We're told Catherine had been in Silver Hill Hospital in Connecticut for treatment, but she has checked out.

Catherine Zeta-Jones kept it real and took on the most unlikely role of her life in NYC this morning ... subway commuter.

The 41-year-old bundled up and took her adorable daughter to school via underground public transportation.
CZJ was in "Traffic," but she doesn't deal with it.

Spicy.
We're just sayin'.
Michael Douglas and
Catherine Zeta-Jones took their two kids today on the Flight of the Hippogriff roller coaster as part of the
The Wizarding World of Harry Potter at Universal Orlando Resort.

According to the resort, they also sampled Butterbeer, got fitted for wands at Ollivanders and toured Hogwarts Castle.
You're only as old as you feel.

Neither is of Italian descent.
We're just sayin'.
Catherine Zeta-Jones had no problem filming a scene that subjected a whole lotta children to a prosthetic johnson -- but good luck getting her to justify it.
What parents let their kids hang around a guy who looks like he's exposing his penis near a pre-school?

That's exactly what happened in NYC yesterday, when Catherine Zeta-Jones shot a scene for a movie. Check out CZJ running away from a flasher with two kids under her arms. And look behind the flasher at the extras -- little tykes watching Long Dong Silver showing his prosthetic wang.
So producers paid the kids squat and the parents bit the bait. When the mini-extras go to real school, they'll surely be the hit during show and tell.
Test pilot for the Batman "nipple suit," George Clooney, was out in New York yesterday -- where he voiced his concern over Matthew McConaughey's future baby bump. Hell, Schwarzenegger was
pregnant once ...
Also in New York: former Fugee Wyclef Jean, a toned Tony Bennett, Catherine Zeta-Jones' main squeeze and the terrific Tommy Lee Jones.
Look out! It's a Gotham City Star Catcher!
Michael Douglas and Catherine Zeta-Jones really made one TMZ photog work hard for the money shot last night -- faking him out at Xi'an in Beverly Hills.
The A-listers exited the restaurant, to find that the valet had brought the wrong white SUV for them. It appeared that Michael didn't know if the boxy ride was his or not, until the valet said it was a Land Rover ... Douglas owns a sleek Lexus.
The two went back inside the restaurant and our photog waited for the right car to pull up -- it never did. Douglas and Zeta-Jones ended up sneaking out the back -- but TMZ ran back there just in time to get a quick wave from Catherine as they took off!
Disco Cisco Adler was seen Tuesday night, kissing all over Paris Hilton, but as he left Les Deux, he was sooooooo over it! When asked how Miss Hilton she was doing, Adler blew off the question. How ballsy!
DJ Sam Ronson was seen outside Hyde, doing her best Run DMC impression. Elsewhere in La La Land, Haylie Duff and a very creepy Nicole Richie look-alike were spotted outside a Tweety Boutique Launch party.
And in New York, the Coreys were at Marquee to "celebrate" their show, and to fete Feldman on his 36th birthday. All this and more in today's bicoastal birthday blitz edition of Star Catcher!
Move over Lindsay, Paris, Nicole and Hayden -- all of whom didn't even make the shortlist -- and make room for Raquel Welch! A new poll from E-Poll Market Research and reported on
Forbes.com found that the average age of Hollywood's hottest is 36 -- and hot grand-ma-ma Raquel tied with youngin' Jessica Biel on a new poll of Hollywood's hottest celebs.

Latina leading lady Salma Hayek topped the survey: more than 65 percent of respondents reported that they considered the 40-year-old "Frida" star sexy. Also over 40 and on top of the sexiest poll: Pam Anderson, Elizabeth Hurley and Halle Berry. Jennifer Lopez and Catherine Zeta-Jones, both 37, scored sexy accolades as well.

Several Bright Young Things -- both Jessicas (Alba and Biel), and Alyssa Milano -- made the list as well. But by and large, America loves its stars grown and sexy: Poor Angie Jolie came up dead last!
