FATHER’S LITTLE HELPERS: A fashion week sighting of Alexandra and Theodora Richards isn’t particularly rare — the former’s been spotted at BCBG Max Azria and Julie Haus thus far, but seeing their father, Keith Richards, is another story. The Rolling Stone and his model wife, Patti Hansen, stopped by Rose Bar on Wednesday night for a party for jewelry brand Hearts on Fire, where the couple’s daughters were manning the DJ booth. (Fellow rock royalty Liv Tyler was the fete’s co-host and the likes of Leonardo DiCaprio, Alan Cumming, Mena Suvari, Adrian Grenier, Sean Avery, Emma Roberts, Tara Subkoff and Mickey Rourke made an appearance. “I rarely get to see him so it was nice to spend some time together,” said Theodora Richards, the eldest of Keith’s kids, afterwards. “I watch him perform and it makes me proud,” added younger sister Alexandra. “It’s the same for him.”
BOOK ’EM: Maggie Rizer is hard at work on a memoir that will detail the ups and downs of growing up in the modeling business, as well as the highs and lows of her personal and family life. Due out next spring, the book’s working title is “Model Behavior,” but the strawberry blonde hinted at its complexity. “It’s kind of emotional to go through it all, and I’m doing it myself. There is no ghostwriter,” she said before watching Nicole Miller’s show Friday. The front-row seat suited her just fine. “When you’re watching a show, you can actually see the clothes, hair and makeup. When you’re walking in one, you don’t see anything,” Rizer laughed.
