The 25-year-old pop star, who is known for her glowing skin, says she has bad days just like everyone else and often cuts out booze in order to clear up her pore, reported Contactmusic.
"When I feel like my skin has had it, I cut all the alcohol completely and overdo the water. The morning of the Chanel couture show last year, I was so jet-lagged that I really didn't sleep, and I had some wine the night before. I was like, 'Oh my God, I look old as shit! Who is this person?'," Rihanna said.
