Lindsay Lohan did it in Las Vegas this weekend. So did Khloé Kardashian.
Lohan celebrated her spray tan line, Sevin Nyne, and her 23rd birthday with a day at the MGM Grand Hotel & Casino's Wet Republic pool. Joining her for the festivities were folks like her brother, Michael Jr. and bestie Brittny Gastineau.
Hotel staffers surprised Linds with a red, white and blue birthday cake.
Meanwhile, on Friday night...
Kardashian toasted turning 25 with sisters Kim and Kourtney, brother Rob, mom Kris and Kim's football star boyfriend, Reggie Bush, at Pure nightclub. (FYI: Don't forget—Kourtney & Khloé Take Miami premieres Aug. 9 on E!)
They enjoyed mucho Veuve Cliquot champagne and Belvedere vodka.
