I don't even want to know how much time Cher has spent at the plastic surgeon's office over the years, but the results are pretty impressive! With the amount of work she's had done, you'd think she'd come out looking like Catwoman, but her doc must be the best in the biz because she looks AMAZING!

Cher was spotted leaving Cirque du Soleil's Kooza in Santa Monica over the weekend, and as always, the pop legend looked much younger than her 63 years. She's admitted to plastic surgery in the past, but we have to wonder what else she's doing to look this fabulous!

The queen cougar has definitely sunk her claws into her new biker boy-toy Tim Medvetz, and an X17 photog says Cher and her 24-years-younger guy were so in love at the Malibu fair last night that they looked like a couple of teenagers!

Says our guy, "They were all over each other! She looked like a teenager, excitedly jumping around him. At one point, they were sharing a drink. She was drinking through the straw, then she put the straw in his mouth, back in her mouth and repeated it several times, really fast. She's definitely in love."

Ok, after reading that, I'm sure you're gagging a little, but this is Cher, the original cougar! Nothing out of the ordinary about that!

Kate Hudson's 20's went out with a bang last night! The soon-to-be 30-year-old (her actual birthday is Sunday) had a crazy party last night in the Palisades, where the cops were called after 1:30 am when neighbors complained of loud music!

Everyone from Gwen Stefani and her ex-boyfriend Tony Kanal, Demi and Ashton, neighbor Adam Sandler, Jessica Alba, Matthew McConaughey, Rachel Zoe, and Leonardo DiCaprio came out to celebrate. Side note: Gwen and her ex came to the party together...and Gavin was nowhere in sight.

OH, and Cher climbed out of her coffin to come to the party, too:

Cher has put her Italian Renaissance-style Malibu mansion on the market for $45 million, according to The Wall Street Journal. The 14,000-square-foot, three-story house has six bedrooms, seven bathrooms, a theater, a gym, multiple verandas, a tennis court, a pool and a guest house.

This is just one of many properties the singer owns, and she has bought and sold several homes in the past few years. In 2006, she purchased a condo in Los Angeles, and in the same year she sold her waterfront pad in Key Biscayne, Florida, for $8.8 million.

Since May of 2008, Cher has been performing at Caesars Palace in Las Vegas, which used to be fellow diva Celine Dion's old gig.

Cher needs to calm down! Her advice to Brit is the blow up the paps with a car bomb!!!

What ever happened to the peace and love of the good 'ol days with Sonny?

Fire tore through Malibu yesterday and celebs evacuated. We've compiled some pix of a few of the stars who live in Malibu so you can see just what's at stake here -- homes worth tens of millions, in some cases, and obviously their possessions and safety are threatened. Best of luck and safety to all our Malibu pals ...

Lucky for Britney, she's already outta there ...
