We just have to say it: Nicole Richie's kids are pretty adorable.
Richie and her husband, Joel Madden, took their two tots -- Harlow, 4, and Sparrow, who will turn 3 next month -- to a birthday party in LA on Saturday. Harlow, wearing a pink princess dress, stuck by her mom's side to check out her phone, while Sparrow, donning a pirate outfit, got some laughs in with mom as well.
But Richie and Madden weren't the only stars at the birthday bash. Uncle Benji Madden stopped by the festivities, while Tobey Maguire and his wife, Jennifer Meyer, took their kids to the party too.
