It was a Hilton family affair.

Kathy, Rick and Paris Hilton — along with Paris' current squeeze Benji Madden — were front and center Tuesday at the Mercedes-Benz L.A. Fashion Week show for Nicky Hilton's high-end Nicholai line.

Before the models took the runway, mom Kathy mingled with the crowd, dad Rick snapped iPhone photos and big sis Paris exchanged whispers with Madden, the Good Charlotte guitarist.

The latest designs from the younger Hilton sister included trench coats, knit tops, houndstooth accents and lots of leather trim. Nicky debuted the more-expensive Nicholai line at New York Fashion Week last year. She launched her first clothing line — the casual Chick by Nicky Hilton — in 2004.
