"My beauty tip is bronzer. Regardless of whether you're light-skinned or dark-skinned, wear bronzer. Put it on the periphery of the face, the décolletage, and the cheeks. It always makes you look like you just came from Ibiza! As for my Fitness tip: Corsets!"

"My number-one beauty tip is to mix Estée Lauder Advanced Night Repair with foundation. It just turns every foundation into the most sheer amazingness. For fitness, I do a lot of yoga. I love yoga. I think it’s so good for your mind and body, as well."

"For beauty, get enough sleep. That’s the most important thing. I like to go to bed early, so I average about seven hours a night. For fitness, I work out every day. I think that’s also good for your balance and your mind. I do Tracy Anderson and SoulCycle."

"Moisturize a lot. During the morning, I tend to mix Estée Lauder Advanced Night Repair with Estée Lauder Resilience Lift Firming/Sculpting Face and Neck Lotion Broad Spectrum SPF 15. I do that throughout the day and it really, really helps. For fitness, mix it up and always remain active. I mix boxing with cardio and pilates. If I’m not busy or working, I’ll work out every day. If I am busy, I’ll try to at least sneak in 30 minutes or try to work out every other day."
