This is 58! Lisa Rinna celebrated another year around the sun in Mexico with husband Harry Hamlin this week — and shared a sizzling birthday selfie in a plunging white swimsuit on Instagram on Monday, July 12. To celebrate 58, the actress rocked a white one-piece from designer Norma Kamali and yellow-tinted aviator sunglasses from Tom Ford, captioning the post: “This is 58,” complete with celebratory emojis.
