Beyonce Knowles got to play sexy cop on a set in Harlem, NYC, yesterday afternoon. The law's not the only thing Beyonce's laying down this week — she's been working on her upcoming album, which will be released Nov. 18. The first two singles, "If I Were a Boy" and "Single Ladies," will be out Oct. 7. Perhaps the most exciting tidbit about her new music is that she's been in the studio recording with Justin Timberlake this week! They looked great together on stage at Fashion Rocks last weekend, so there's sure to be something hot coming our way from these two superstars.

Liv Tyler watched as Milo ran ahead of her to chase a pigeon down the streets of Manhattan yesterday. She hosted a Fashion Week event at Rose Bar on Wednesday, but Liv looked like she was having just as much fun dressed down and playing with her son. Liv recently spoke about being in limbo after her split with her hubby Royston in May, but luckily she's got her little buddy by her side to make things easier.

Christian Bale shopped for motorcycle gear at Alpinestars in LA yesterday, loading boxes onto his pickup truck and changing right into his new pants. The actor looks ready to hop on the Batpod in his gear, which is perfect for the news that The Dark Knight will be re-released in January. Looks like Christian and his costars are going to be on everyone's mind during Oscar season, but to hold us over until then, we can enjoy watching the actor with his fashionable real-life sidekick.

Eva Mendes took a break from all her Fashion Week duties last night to attend a screening of The Women in NYC with her costars Jada Pinkett Smith, Meg Ryan, and Debi Mazar. Unlike last week's big premiere in LA, Annette Bening and Debra Messing sat this one out, but Julia Stiles and Bette Midler stepped in. Even Mick Jagger, who is one of the film's producers, joined them for the afterparty at the Gramercy Park Hotel — though it probably wasn't hard to convince him to spend the evening surrounded by beautiful ladies. The reviews for this movie aren't exactly raves, but hopefully the all-star women cast can still bring out the audiences.
