Now that it's been confirmed that Penelope Cruz and Javier Bardem are engaged, we're betting that this stunning sparkler is the rock!

Pene stepped out in NYC last night, and she made no effort to hide her bling as photographers snapped away. While it's not your traditional diamond ring, it's a pretty hefty gem and it's certainly on the right (or in this case, the left) hand!

Kari Ann Peniche, the woman who was exxxposed in the "naked tape" with expectant parents Eric Dane and Rebecca Gayheart denied former rehab roommate Mindy McCready's claims that's she's a madam and a prostitute.

“I’ve never been a madam. I’ve never been a prostitute,” Kari Ann told Access Hollywood's Shaun Robinson. “Mindy is the craziest person I have ever met in my entire life. Like, she’s insane.”

But although Kari Ann fervently denied the claims, she didn't seem willing to go too far to clear her not-so-good name.

"To say somebody is a prostitute is libelous,” Shaun told Peniche. “Nobody’s suing Mindy for saying these things, these liable, horrible things. Why? Why is that not happening?”

“I don’t know… I have no idea,” Kari Ann began. "But what am I going to gain from it? You know?”

"Your reputation," Shaun replied. (Well played, Robinson.)

“I just think the truth is the truth,” Kari Ann replied. “Karma is like good enough and you know, I mean if it continues then you know maybe I’ll have to do something about that.”

Yeah, after that, we really believe that "karma" is currency Kari Ann trades in!

Jen Aniston was back on the set of The Baster, working on reshoots in LA with co-star Jason Bateman.

Sometimes reshoots are totally standard, other times it's because there's an epic fail with some of the material - which do you think this is?

Troubled starlet and out-of-work actress Mischa Barton has gone straight from The Beautiful Life to the wasted life, partying at a LES bar with Young Veins' front man Ryan Ross.

A spy tells the NY Daily News that the model slash actress was buying shots for her pals (including Ross) at Randolph on Wednesday night.

"She had a drink in hand all night," said the source, "and she and Ryan looked very friendly."

Unemployed actresses (let alone ex-rehabbers) should probably not get into the habit of buying their new rockstar boyfriend drinks!

If Lauren Conrad was at the doctor's office, or getting her car washed, I can understand why she might be covering her face, but if you're a celeb strolling down Robertson Blvd for a little retail therapy, you're totally fair game for the paps!

Yesterday Lauren stopped by Intermix, and rather than making a series of sour faces like she usually does, she covered up her mouth like she had something to hide. A zit? A cold sore? Or is she STILL pretending that she doesn't want to be photographed?

David Hasselhoff has fallen off the wagon in a big way, at pal Simon Cowell's big birthday bash in London.

The Sun reports that the Baywatch star got so out of control after drinking for days (starting with Cowell's party last weekend and continuing at London's St. Martin Lane Hotel), that his assistant had to call in a doctor to deal with the belligerent star. But David was none too happy about this latest intervention and lashed out, accidentally punching the doc in the face.

A source tells the paper, A source close to the star said: "David is very hard to handle when he drinks, often very emotional and aggressive. On this occasion he became so drunk he wet his hotel bed - ruining two mattresses - and was becoming a real pain for staff. His assistant Joe Townley was so concerned he called out a doctor. David was furious and lashed out at him - but mistakenly hit the doctor. They decided they had no option but to lock him in the basement until an ambulance arrived."

The Hoff was taken to Capio Nightingale Hospital, spending two nights in a private suite before being discharged yesterday.

Last month, David denied being hospitalized for alcohol poisoning, calling it a bad reaction to medication instead. But it's undeniable that after this incident, the Hoff needs serious help.

Last night Paris and her hunky boyfriend Doug attended the Carnival At Bowlmor Lanes Grand Opening, and after smiling for the cameras on the way to the red carpet, Miss P then switched into sexy fierce mode and gave her very best blue steel. Make that blue leopard steel!

Work it, girl!

President Barack Obama has won this year's Nobel Peace Prize for his "extraordinary efforts to strengthen international diplomacy and cooperation between peoples," the annual award's committee said in a statement this morning.

Thorbjorn Jagland, the chairman of the Norwegian Nobel Committee added, "We are not awarding the prize for what may happen in the future but for what he has done in the previous year. We would hope this will enhance what he is trying to do."

The only other sitting US presidents to win the award were Theodore Roosevelt and Woodrow Wilson.
