Not a bad way to spend the day!

In between dinners and Art Basel events, Paris Hilton and River Viiperi soaked up the sun in Miami on Friday. River tweeted, "Chilling by the pool with my Beautiful blondie @ParisHilton #Miami #lovinglife #Dreamscometrue"

Wonder where these two lovebirds are headed for Christmas? Aspen? Tahiti? We know Paris is happiest in a bikini with a beach a few hundred feet away, so maybe both!

Jennifer Garner ran errands with daughter Seraphina and then headed to a lunch meeting in Beverly Hills on Friday, and at first glance we gave Ben's wifey a thumbs up for her classy getup, but then she took off her trench coat:



Sigh. This is maybe one step up from her old mom jeans. What would her stylist Rachel Zoe say?!

Kourtney Kardashian was snapped leaving her hotel for a lunch date on Friday, but not before giving us a peek at her beautiful booty in a pair of tight leather pants!

Kourtney is still in Miami filming her reality show with sister Kim, and while the focus this season is on the older Kardashian sisters and the opening of their new DASH boutique, Khloe will be making some appearances as well. And the best part? The new season will premiere in just a few weeks!

How boring!

Then again, considering that he beat the crap out of fiance Halle Berry's ex-boyfriend/baby daddy Gabriel Aubry on Thanksgiving, being boring might be just what the publicist ordered!

A rather pensive Olivier Martinez was spotted checking out the goods at Fast Frames in Beverly Hills on Friday, and interestingly enough, he's no longer sporting his hand cast. Guess his "injury" wasn't so bad after all!

A preggers Petra Ecclestone and her sister Tamara went shopping at the Grove in Los Angeles yesterday, and naturally, the heiresses hit Barneys New York. But were they buying pricey duds for themselves or someone on their nice list? Perhaps a little bit of both?

Though Petra has yet to officially confirm the pregnancy herself, that growing baby bump says it all! This will be the first child for Petra and her hubby James Stunt, who tied the knot in 2011 after 4 years of dating. Congrats!

Kim Kardashian's 4-month-old kitten Mercy, who was a gift from boyfriend Kanye West, has been put down, the reality starlet confirmed on her blog.

After learning that she was allergic to the cat, Kim gave her to sister Khloe's assistant Sydney Hitchcock in September. When the teacup Persian came down with symptoms of a "cancer-like virus often associated with breeding," Sydney decided to have her euthanized.

"My heart is completely broken," Kim wrote. "I had fallen SO in love with Mercy that I wanted to try everything I could to keep her but I didn't think it was safe to resort to injections, and it wasn't fair on Mercy, because I couldn't play with her or give her as much attention as I wanted to. Mercy deserved a mom who could really give her the time and affection she deserved. I knew that Sydney, Khloé's assistant, who had recently lost a cat she had loved and cared for for 17 years, would be the perfect mom for Mercy and Sydney was so excited to have Mercy as her own!"

"They discovered she had a stomach problem that we weren't aware of," Kim continued. "Poor little Mercy died the very next day. It broke not only my heart that little Mercy died at only four months old, but Sydney's too. Mercy was a gentle and loving kitten and we are all going to miss her so much. Thanks to Sydney for making Mercy's short life one filled with love. RIP Mercy Xo."

Make that a Mickey Mouse muscle tee with a serious twist!

Justin Theroux hit the gym in West Hollywood on Friday, and the 41-year-old writer/actor gave us a peek at what Jennifer Aniston gets to see everyday when we snapped him leaving.

Oh, and get this ... Justin was drinking Smartwater! Jen probably has a lifetime supply at their house, so why not?

Brooke Mueller was hospitalized this afternoon after an assistant found her napping and unresponsive. Brooke's rep tells X17online.com:

"An assistant thought Brooke was non-responsive while she was napping and hastily called an ambulance. As a precaution, Brooke was brought to a local hospital and discharged after an hour. She was diagnosed with exhaustion and dehydration and is now fine and resting at home. That's it."

Mueller, Charlie Sheen's ex-wife, has been in rehab numerous times and most recently completed an in-patient treatment program in April. Mueller married Sheen in May 2008 and gave birth to twin boys Max and Bob in 2009. The couple divorced in May, 2011.

X17online caught up with Brooke last night at Mr. Chow, as she was on a date with her new boyfriend, jewelry designer to the stars, Pascal Mouawad.
