While Angelina Jolie was shooting scenes for The Tourist in Paris, we caught Brad Pitt and daughters Shiloh and Zahara indulging in a little shopping spree across town. As usual, the girls were looking adorable, and even though Brad looks like a cross between a bum and a private investigator, he still looks pretty handsome!

Think they're going to go watch mom on set one of these days? Or perhaps Brad isn't too keen on them seeing some of Angelina's scenes with the dreamy Johnny Depp?

Spotted: An ecstatic Hilary Duff showing off her enormous 14-karat sparkler at Katsuya in Hollywood last night. Of course, the man behind the ring was there too - Mike Comrie was there to escort his million dollar lady love out the door. Yup, rumor has it that's how much the NHL star paid for the rock. It MUST be love!

Jessica Biel looked super serious as she hit the streets of NYC today. Justin Timberlake was nowhere in sight ...

This isn't the Jessica whose character in Valentine's Day says of her Blackberry - "Thank God it vibrates!" Oh no, this is the serious Jess ...

Biel is in the Big Apple after a string of appearances including the VD premiere and b-friend JT's William Rast fashion show during Fashion Week.

Girls Aloud singer Cheryl Cole had her wedding ring back on her hand yesterday as she headed to LAX to return to London and to her husband Ashley after reports he cheated on her (again) recently.

Reports claimed Cheryl had texted her footballer hubby to announce to him she would divorce, but is the report false? Is Cheryl sending a message, after no wearing her ring throughout her week in Los Angeles, that she's ready to go home, to reunite with Ashley, and to patch things up?

Ciara sent a message via her sweater today at LAX as she headed out of town with her fuzzy travel companion.

The sexy singer wore a loose-fitting, black and white sweater with the works "Give Back" emblazoned on the front. What an appropriate message! She just participated in the SOS Help for Haiti fundraiser put on by BET.

Hey, good idea -- do some good, AND look good doing it!

Tiger Woods' plane has been spotted at a small airport in Mesa, Arizona, a town just outside of Phoenix.

Woods and his wife Elin Nordegren and their two children Charlie and Sam are said to have accompanied the golf star on his company's private jet on Sunday, having departed from Orlando Executive Airport, about 20 minutes from Tiger's Windermere home.

During Woods' emotional apology on Friday, Tiger said that he would be returning to rehab immediately. However, The Meadows rehab facility (where X17online initially reported Tiger was seeking treatment) is an hour and a half away from the Mesa airport by car and Wickenburg (where The Meadows is located), has its own airport that can accommodate a Gulfstream GV.

Cottonwood de Tuscon, Arizona's other posh rehab facility is also host to several airports.

So is Tiger really returning to rehab? If so, which one? And why would his family be with him? Or has he traveled across the country to return to golf? The Waste Management Phoenix Open starts in Scottsdale on Thursday ...

Brooke Mueller has entered another LA-area drug and alcohol treatment program after checking out of The Canyon facility in Malibu over the weekend.

A source tells X17online exclusively:

"After learning The Canyon Treatment Center had wrongfully breached her privacy, Brooke Mueller was left with no choice but to leave the facility and immediately and checked herself into a new, undisclosed location to continue her treatment".

Husband Charlie Sheen, meanwhile, attended his father's performance of The Subject Was Roses at a downtown Los Angeles theater last night.

So where is Brooke now? Our source is remaining tight-lipped about Mueller's whereabouts but there are only a few places she could go, really ... there's the famous Promises in Malibu, where Britney spent some time; Passages, also in Malibu, where Mel Gibson admitted himself after his DUI arrest; or Cliffside, again in the 'Bu, which seems really luxurious and claims to host celebs, but hasn't seen any of them there recently that we know of. Then there's a Valley rehab -- Las Encinas Hospital in Altadena where Jack Osbourne went in 2003 but we're thinking that's not likely ...

Wherever she is, she's in the right place and doing what needs to be done!

Despite reports of a breakup, Kourtney Kardashian and baby daddy Scott Disick are hanging tough. Here the two are glamming it up over the weekend at JET Nightclub in Las Vegas for K's DASH fashion show at The Mirage.

So what's the deal? Are these two putting on a show for the cameras? Just last week, Kourtney confirmed that the two are still an item...and by the looks of it, Scott's got a firm grip on his lady!

Where's baby Mason? Hmmm..maybe Auntie Kim is pulling some babysitting duty. But it looks like Kourt has already shed that baby weight. And she's sporting a dress of her own design for Bebe) Way to rock the one shoulder!

You know what they say...a couple that parties together, stays together. Well, at least that's what they say in Vegas.
