Lovely ladies were showing their stuff this week on Twitter -- sharing some intimate and very sexy photos with their fans.
"Buffy the Vampire Slayer" alum Charisma Carpenter flaunted her ridiculous bikini body, slipping her 43-year-old body into a skimpy two-piece. Yep, we said 43.
59-year-old Christie Brinkley also defied age in her swimsuit, posing alongside daughter Alexa Ray Joel ... who also looked fantastic!
Plus: Lindsay Lohan posted her first selfie since leaving rehab, Will Smith hung out with an unlikely teenager, Mariah Carey played with her pooches and Khloe Kardashian suited up as a Sumo wrestler!
