Actress (and aspiring gym entrepreneur!) Gwyneth Paltrow was kind enough to post a list of her favorite restaurants and hotels on that new lifestyle website of hers, Goop.com. Lots of the usual suspects are mentioned, like Balthazar and Babbo, which is owned by her food travel show co-host, Mario Batali, naturally. The hotels reflect the places she's lived for the past year while her apartment is being renovated. (That sounds cost efficient!) So where has Gwynnie spent the past 12 months? She says she's only mentioned the places she "loved," a list that includes the Lowell, Bowery, Carlyle, Mercer, and the Inn at Irving Place. But she throws in the Greenwich Hotel, too, although she admits she's yet to see the place. "It looks good on the website anyway." Good enough for us! [Goop via Eater]

Jerry and Jessica Seinfeld heading into the Waverly Inn, where they had dinner with Madonna and Gwyneth Paltrow ... Paul McCartney signing autographs on the street ... Liev Schreiber pushing son Alexander in a stroller and carrying groceries ... Agyness Deyn walking in the East Village with a cup of coffee ... Blake Lively and Penn Badgley on the set of Gossip Girl ... Heather Mills shopping with daughter Beatrice and boyfriend Jamie Walker ... and Salma Hayek arriving at JFK with daughter Valentina.

It wasn't a joke: Gwyneth Paltrow really is planning to open a gym with her personal trainer, Tracy Anderson, the same woman responsible for Madonna's freakishly muscular arms. Paltrow's publicist tells the Daily News that the gym will be located in Tribeca. But don't expect to see Gwynnie in person when it eventually opens: When she went on Oprah last fall with Anderson, she said her "favorite gym in the world" was the one located in her own home.

To all those critics of Gwyneth Paltrow's GOOP, the inane newsletter and website that serves as a repository for Paltrow's infinite wisdom, know this: Gwynnie "feels sorry" for you, since you probably haven't had a life as "blessed" and "unique" as hers. [USA Today]

It was inevitable from the moment Gwyneth Paltrow named her website "Goop" that it would come to this: advice from the movie star on bowel movements. Stop reading now.
