What called for a Friends reunion? Last night's L.A. Modernism Show & Sale opening night, which benefited the Los Angeles children's arts organization P.S. Arts (Tommy Hilfiger is an avid supporter). Lisa Kudrow and Courteney Cox reunited to enjoy the evening, which raised funds for the non-profit's dance, music, theater, and visual arts programs that serve 12,000 students throughout Los Angeles County and the Central Valley.
