Happy Birthday, Harlow Madden! Nicole Richie and Joel Madden‘s little girl turns 3-years-old today! Wow, does the time fly! She celebrated with all of her A-list friends — including Mason Disick, Zuma and Kingston Rossdale and Honor Warren — during a birthday bash at The Treehouse Club in L.A. on Saturday (Jan. 8), but today we’re sure she’ll spend some quality time with her Mom, Dad and little brother Sparrow, 1!

“Harlow is very great with him [Sparrow] and very gentle,” Nicole says of her daughter. “They are best friends.” As for her birthday party, it sounds like Harlow had a fantastic time! “It was a fun, casual party,” a source tells People. “Besides the celebrity kids, Harlow had a few friends from school at the party and she was very excited. The kids played outside in the Treehouse and enjoyed art and crafts projects inside. All the moms chatted while the dads bonded and it was a perfect party for both the adults and the kids.” We hope Harlow has a wonderful 3rd birthday!
