Salma Hayek, 55, is looking better than ever in a bikini — but the actress wants people to know why she’s been posting up her sexy swimsuit snaps. “I had to lose a lot of weight and exercise to get into the bikini towards the end of last year,” Salma confessed in a recent interview with Entertainment Tonight. While she didn’t detail how much weight she shed, she has been looking absolutely amazing in all of her photos from this year — especially on her vacations.
