LINDSAY: DEEJAY FOR A DAY
Lindsay Lohan added spin doctor to her résumé at her Feb. 18 N.Y.C. wrap party for the drama Chapter 27 at Level V. To the cheers of cast and crew (including a still-chunky Jared Leto, who put on over 50 lbs. to play John Lennon's killer, Mark David Chapman), her mom, Dina, and pals like Jamie-Lynn Sigler and Cuba Gooding Jr., Lohan got the bash bumping around 1:10 a.m. After a bodyguard escorted her across the congested dance floor to the deejay booth, she stripped off her black leather bomber jacket, donned a pair of fingerless deejay gloves and launched a 40-minute set (see below). Mixing classic rock and the latest hip-hop, Lohan danced along, did some turntable scratching and even gave club co-owner Eugene Remm a few pointers as he briefly took control while she posed for pictures with friends. Elated by the experience, Lohan slid back into her roped-off VIP "cave" to party with her guests until almost 3 a.m.

BIRTHDAY GIRLS
The West Coast shone with candles last week. Denise Richards rang in her 35th with pals like John Stamos and gifts from L.A.-area boutiques Sweet Peach and Planet Blue at Nobu in Malibu Feb. 17. The next day Haylie Duff got a Chanel clutch from little sis Hilary while celebrating at L.A.'s White Lotus. Hilary says their mom went "a little crazy," buying 21 items for Haylie's 21 years. That night Jennifer Love Hewitt's 27th was feted by a party of 14 at Little Buddha in Las Vegas.
