Kourtney Kardashian and little Mason shot scenes for their reality show in Miami on Monday at the Eden Roc Hotel, and later we spotted the two relaxing at the pool with daddy Scott Disick.

On Tuesday Kourt hit the gym with her sister, and she tweeted, "Good morning workout with @KimKardashian! She is my workout mentor. No one has drive like her."

And maybe Scott has something to do with this, but Kourt was in an uncharacteristically good mood:

There's a reason she's a supermodel!

Kate Moss stepped out in London yesterday in a chic black velvet coat, dark denim, and leather boots, and we absolutely love how the blonde beauty makes looking beautiful so effortless!

After opening up to Vanity Fair last month about her personal life, the Calvin Klein icon might be sharing more intimate moments in a new documentary about her life, according to recent reports.

We would die to get a glimpse into her private world!

January Jones and her son Xander were snapped lunching at Houston's in Pasadena on Monday, and the Mad Men star showed off her newly dyed brunette locks!

This isn't the first time January has played around with her hair color. Back in June she went from platinum blonde to red, and while that hue was reportedly for a film role, still no word from her reps on why she went to the dark side. Maybe Betty Draper is going for a daring new look to piss off Don? Or January just wanted to switch it up for the winter? We'll keep you posted!

Most people look kooky with black-rimmed glasses and no makeup, but not sexy model Kate Upton.

The gorgeous blonde left her makeup at home while cruising through JFK airport in New York.

Kate was all smiles while wearing skintight black pants, a satin blouse, creme-colored sweater .... and carrying a blue handbag.

Work your natural beauty, girl!

Looks like quite the palatial pad!

Jennifer Aniston and fiance Justin Theroux purchased this Bel Air mansion at the beginning of the year, but before they move in, the love birds want to make sure their love nest undergoes all the necessary renovations!

Construction is in full swing on the 8,500 square foot property, and it is expected to be completed by early 2013. The Friends actress is already hard at work furnishing her future residence, though, as she was recently spotted shopping for home wares with her beau.

The engaged couple's abode sits high atop the Santa Monica mountains and overlooks the Pacific Ocean. It is part of a gated community with neighbors that include Nicholas Cage and Lauren Bacall.

Only Miss Aniston would rip out an on-site vineyard to add a pool and jacuzzi. The 43-year-old must have needed a place to tan her hot body!

The price for this mansion?

A whopping $21 million!

Naomi Watts has a gorgeous back, and the blonde beauty was proud to show it off at the UK premiere of The Impossible in London, England.

Watts strutted her sexy stuff on the red carpet in a black Tom Ford gown with voluminous draping sleeves.

She stars opposite Ewan McGregor in the flick which is set during the 2004 Thailand tsunami. The Impossible hits theaters next year.

Khloe Kardashian returned home to Los Angeles last night from Miami, and as soon as she landed, she was practically mobbed by photographers. Khloe's certainly not a diva with photogs like her sister Kourtney can be, but even she seemed a little bit surprised with the amount of attention she received!

So how will the reality starlet be spending her Thanksgiving? Sadly, not with hubby Lamar Odom! On Thursday, Khloe will be on the set of The X Factor while Lamar will be in New York, as the Clippers are playing against the New Jersey Nets on Friday.

Khloe told People, “Honestly, I’m fine with it, because I’m obsessed with my husband – in a healthy way – but he’s on the road. He has a game in Brooklyn, so I don’t feel guilty, like, ‘I’m not going to be able to cook for him.’ So, he’ll be on the road. He’ll be working anyway. So, I feel better about that, and my sister Kim will be here. And I think my mom will come here that night, too. Thanksgiving at The X Factor!"

So what did she have to say about Kim's tweets regarding the Israel-Gaza conflict? "She didn't mean any harm," she told our videographers before she hopped in her car.

Anything to get the judges' attention during semi-finals!

On last night's episode of Dancing With the Stars: All-Stars, all eyes were on Val Chmerkovskiy and celebrity partner Kelly Monaco during their surfer-themed Flamenco routine. The two started off wearing more ahem, traditional outfits, but after a few minutes both dancers ripped off most of their clothing and Val even splashed around in a kiddie pool!

"Kelly, I think you've been upstaged by the Speedos," judge Bruno Tonioli said. "Never work with Speedos or animals!" So what about the smooch they shared at the end? "It was part of the choreography!" Kelly told Us Mag. "We could have done anything but we thought that fit and we picked that."

This week, each pro/celeb pair had to do two dances: One was an "offbeat challenge" while the other was a tribute to the late Michael Jackson. MJ's mother, Katherine, was in the audience, and we're guessing she liked the tribute to her son, but probably didn't know what to make of the Magic Mike-inspired dance!

So who will be sent home next? We'll find out tonight! Check out Val and Kelly's routine below:
