Baby Delilah is one lucky little girl!

Kimberly Stewart went shopping at French baby boutique Bonpoint on Rodeo drive for her 3-moth-old baby daughter -- Benicio del Toro is the daddy --- and we're betting she already has a wardrobe that rivals Harper Beckham's!

While Stewart is no longer dating the Oscar winner, she tells Hello! mag: "Benicio's very involved; he and Delilah have a very special bond."

Kimberly named her daughter after Tom Jones' 1968 song "Delilah".
