So many special memories since we were little girls! Sending you lots of love, happiness & birthday wishes! Love always Paris,” Hilton wrote alongside the photo (fittingly, she included birthday cake and twin emojis) The Candidly Nicole star also received birthday wishes from her biggest cheerleader: her father, Lionel Richie. ” all grown up ! I’m so proud of you Happy Birthday “My Ballerina Girl” @nicolerichie,” the singer captioned a heartwarming photo of himself kissing his daughter on the cheek. Lionel has supported his daughter through thick and thin. And Hilton, though sometimes estranged from Richie, has remained a staple in the star’s life. The two socialites have been close since birth and even starred together in The Simple Life in the early 2000s. Although they’ve had their feuds over the years, Hilton’s Instagram suggests the friendship has stood the test of time. Earlier this year, Hilton posted an adorable throwback photo to Instagram of herself and Richie in their younger days, wearing fairy costumes and smiling for the cameras.
