• Pete and Ashlee Simpson-Wentz made the new parent pilgrimage to New York's FAO Schwarz, where 6-month old Bronx Mowgli was the center of his parents' attention. Mom and Dad helped him "ride" a life-size plush pony in the store, and baby Bronx was so eager to read books that he tried to turn the pages himself. The musical mom and dad picked out a Stack & Pull toy, a Sporty stroller and Barefoot books with sing-a-long CDs for their little rocker.

• In Paris to promote Hannah Montana: the Movie, Miley Cyrus also made sure she took time to play tourist. The starlet stopped by the Louvre, its gift shop and Café Marley during her downtime. Cyrus also hit up the Champs-Elysees for some clothes shopping at Zara, where she attracted a crowd of 200 within 30 minutes of her arrival!

• Cameron Diaz, helping pal Lake Bell celebrate her 30th birthday with a Guns N' Roses-themed bash at Hollywood's Lucky Strike Lanes & Lounge. Slipping in the side door, Diaz was dressed in rock 'n' roll glam, while Bell dressed like the heavy metal bride from the band's "November Rain" music video. Party guests jumped into a photo booth to snap pictures in their rocker gear. Also there: Alec Baldwin and Jon Hamm.

• Megan Fox, taking in Britney Spears's Las Vegas concert with Brian Austin Green. Before the concert, the two grabbed dinner at SushiSamba in the Palazzo and "seemed very in love and happy," an onlooker says.

• Gossip Girl's Jessica Szohr danced to sets by DJ D-Nice and mur.mur at the Borgata Hotel Casino & Spa during her first trip to Atlantic City. The actress went shopping at the Shoppes at the Water Club, and even wore some new purchases to dinner at Izakaya.
