Kelly Osbourne shows off her post-breakup body while partying at Haze Nightclub in Las Vegas ... and we gotta say, girlfriend is looking fab!

Wearing a short, form-fitting blue dress, Miss Osbourne showed that sometimes a breakup does a body good.

Earlier this week, Kelly and fiance Luke Worrall split over reports that Luke was caught cheating. Immediately after the news got out, she expressed her candid feelings through her Twitter page.

Revenge is sweet!

Check out another photo of a very-svelte Kelly after the jump ...

While attempting to perform a slingshot stunt for her Funhouse tour, Pink was dragged offstage in Nurnberg, Germany, and into a barricade which sent her to the hospital in the middle of her show.

In the above video, you can see Pink's backup dancer/assistants getting her ready for the stunt, but she wasn't properly clipped into the slingshot, and got dragged offstage.

"F*ck that hurt," you can hear her saying as she's down on the ground.

But luckily, the singer sustained no injuries.

Last night, she tweeted, "To all my nurnberg fans- I am so so so sorry to end the show that way.I am embarassed and very sorry. I'm in ambulance now but I will b fine." She continued, "didn't get clipped in2 harness correctly,drug me off stage, fell in2 barricade. Getting xrays.I hope it at least looked cool!!!"

Then later, she confirmed that everything was all good. "Ok all my lovers out there- nothings broken, no fluid in the lungs, just seriously sore... okay. full steam ahead people.no pain, no gain. or is it no brain, no pain? either way, i will be on that stage, even if i have to crawl:)"

Looks like Pink will live to get slingshot another day!

Last night Samantha Ronson paid a visit to her ex girlfriend Lindsay Lohan at her sober house -- and didn't leave until 4am! We know it's technically "not rehab," but is it really kosher for people to be coming and going at all hours and even spending the night? Or is this special treatment for Lindsay?

Lindsay's legal crisis has finally brought her and Sam back together. After a very contentious breakup, Lindsay and Sam barely spoke, until now.

Samantha spent time with her ex at the facility for the second night in a row. But before you think this might mean a reconciliation, Wednesday night, Samantha ended up visiting Lindsay at the same time as her rumored girlfriend, Eilat Anschel! Awkward much?

We asked Samantha how Lindsay's enjoying her accommodations at the Pickford Lofts, and she replied, "Ask her yourself!"

We see Sam hasn't lost any of her sass!

Not like there's anything wrong with that!

Yesterday we spotted Kristin Cavallari sporting a super short strapless dress in Beverly Hills, and even though it's hard to look sexy when you're melting in the 95 to 100 degree weather in LA, Kristin certainly wasn't having any problems! And the flip flops? So California casual...loves it!

Wonder what she's up to? Though Mel Gibson's babymama/ex-girlfriend Oksana Grigorieva claims she doesn't know how the hilariously scary recordings of Mel keep popping up, she certainly seems to be doing a good job staying cool! Yesterday we snapped her at her lawyer's office in Century City, and not only did she keep her mouth shut, but she also covered up her boobies. At least she took some of Mel's advice!

Last night (and for the second evening in a row) we snapped Dina Lohan arriving at Pickford Lofts in LA to spend the night with her daughter Lindsay, who is currently holed up at the sober house as she counts down the days before she heads to jail. No word on whether Eilat or Samantha were invited to the slumber party...

P.S. It's good to see silly faces run in the family!

While this looks like it could be from an episode of Punk'd, we're sorry to report that it's the real deal!

On Thursday afternoon Ashton Kutcher was involved in a collision with another vehicle in Malibu, and thankfully it doesn't look like anyone was harmed, but Ashton's Lexus and the other driver's red mini station wagon definitely need a trip to the body shop!

It's not rehab, but it's Lindsay -- what else did you expect?

Today we snapped Lindsay Lohan leaving her sober living quarters at Pickford Lofts in Los Angeles, and the 24-year-old starlet was still covering up her SCRAM, but she didn't hide her up her face as she was whisked away in a car.

We're not sure what Lilo's been up to since she checked into Robert Shapiro's facility, but she hasn't been tweeting much, so maybe she's just downing ice blended mochas and playing with her art supplies? She better find some way to pass the time, because there's going to be plenty of it when she goes to jail next week!

But will mom Dina come visit her all the time? She did today, but what about when Lilo is behind bars?
