One of the party-goers included model Christy Turlington, who gushed about Paltrow by telling press, “Everybody who’s in her life knows that she’s an amazing cook. There’s not a lot that she can’t do, which I think is pretty clear from all of her work.”

Eva Longoria was spotted leaving a doctor’s office in Santa Monica, CA earlier today (April 14).

The “Desperate Housewives” hottie looked cute and casual with a side braid and aviator sunglasses as she made her way to her vehicle and offered up a quick wave for the paparazzi.

Ashton Kutcher and Demi Moore were arm-in-arm at the launch party for “Real Men Don’t Buy Girls” in New York City on Thursday night (April 14).

Held at Steven Alan Annex, the former “That 70′s Show” star described the effort as “a social media campaign to reduce the demand for child sex labor.”

Ashton added, “There are more slaves in the world today than ever before in history. Sex trafficking is a $32 billion business with the average age of entry into the forced sex trade as 13 years old.”

Having released a short video clip featuring Justin Timberlake earlier in the week, Kutcher’s campaign gives people the opportunity to “pledge themselves against it by putting themselves in a video and pledge to the idea and share the idea that real men don’t buy girls.”

In a recent interview, Courteney explained what it felt like to be back on the “Scream” set, as she said, “It felt natural. We’ve had ten more years of experience of acting, I was that much more confident, I’m now a mom, I’m a different person. Being a different person, feeling a different thing, but coming back to your family who know each other, and you feel like you can get right back into it and be better than you were the last time, and do anything.”

Cox also dished about which traits she and her character share, revealing, “Gail’s kind of campy, and I love her relationship with Dewey, and the fact that there together is great. The fact that he’s so earnest and she’s so out to get ahead it’s just an odd pairing, and so are we – we kind of are – so I love playing Gail. It’s probably the most fun because it’s a real character.”

Ke$ha was spotted arriving to her concert venue in New York City on Wednesday (April 13).

The “We R Who We R” hitmaker hopped out of ehr chauffeured ride as she proceeded to head inside and backstage at the famous Roseland Ballroom.

Using her celebrity status to help causes in which she believes, Ke$ha has also teamed up with PETA to help protect the annual clubbing of baby seals in eastern Canada.

In a statement on the matter, the 24-year-old said, “I was lucky enough to get to watch a bunch of wild seals recently and truly fell in love with these amazing creatures.”

She continued, “Canada gets to be host to harp seals each year during their migration to the ice to give birth which is beautiful and peaceful. But because the babies’ fur is so soft, there are people who club and brutally kill these young animals. The Canadian seal slaughter is barbaric and archaic,” K$ continued. “My music and my fans are part of a movement of youth taking over the world with positive change. I know they’ll help me and PETA ban the Canadian seal slaughter so the only place you see baby seal fur is in a museum.”

Ashley Tisdale was at it again in New York City on Wednesday afternoon (April 13).
