The Post’s Page Six spied Taylor Swift attending the birthday party of the daughter of Blake Lively and Ryan Reynolds at the Fashion Squad School on Warren between Church and Broadway. (Meanwhile *my* spy couldn’t find her phone in time.)

Plus Emily Blunt attended, and it looks like she picked something up for the birthday girl, Inez, who is 7, at Balloon Saloon, which of course shows a savvy shopper.

And a nod to the Lively-Reynolds for supporting local business, when I am sure it would have been a lot easier to do the whole thing in their house.

Of course there’s lots more in People if you want to track more comings and goings, including the bruhaha about Swift and the football player Travis Kelce.

And then there’s a series of stories about Swift’s Franklin Street apartment: BuzzFeed News reported that she loaned it out to Sophie Turner, the English actress who played Sansa Stark in Game of Thrones and who is also in the throes of a divorce from pop star Joe Jonas. The couple are raising two daughters in the city. Also, Swift dated Jonas in 2008. It’s hard to keep up!
