Fall is officially here, according to the latest outings of Hollywood stars.

Whether it’s New York Fashion Week, the kick-off of the school year, or fall television premieres, celebrities are welcoming what the new season has in store for them.

Sarah Jessica Parker, 47, walked her son, James Wilke, to school in New York City while Pippa Middleton, 29, strolled to the gym in her best workout gear.

Who else prepped for the fall?

Date nights were in full effect, too. Eliza Dushku, 31, and fiancé Rick Fox, 43, took in a Dave Matthews Band concert in Hollywood while Jack Osbourne, 26, showed support with his fiancé Lisa Stelly for the Cops4Causes inaugural HEROES Helping HEROES Benefit at Pink Taco in Los Angeles.

Alicia Silverstone, 35, and husband Christopher Jarecki took a break from caring for their little one, Bear Blu, and enjoyed opening night of The Book of Mormon in Hollywood.

One Direction heartthrob Harry Styles, 18, partied in London with Pixie Geldof, 21, — perhaps the two are more than just friends?

Both Janet Jackson, 46, and Jason Biggs, 34, were spotted at the launch of Dylan’s Candy Bar in Los Angeles. The sugary-sweet opening had swarms of stars tasting their favorite candy confections.
