After receiving the present, Richie flew to Vegas with her girl gang including beauty mogul Kylie Jenner, Anastasia Karanikolaou, Amber Asaly, Victoria Villarroel and others.
Giving a glimpse of her girl trip on her Instagram stories, Sofia wrote, "Here we go," alongside a short video that showcased her pretty pink birthday outfit. She donned a blush-colored Chanel co-ord set paired with matching sunglasses, sneakers and a handbag.
As soon as they landed in Vegas, the gang ordered some celebratory drinks with Richie sipping on a summery cocktail.
After getting drunk with her girl gang, they headed to Encore Beach Club at Wynn Las Vegas for a day of fun, dancing and more. From Richie grooving with Alesso at her party to enjoying her much-needed girl time, it's been a memorable birthday already! And it appears there is way more on the agenda.
