Primetime Babes: How Lily Collins, Gabrielle Union And More Stay In Tip-Top Shape

The ageless L.A.'s Finest star avoids soy, gluten and dairy, and follows an "almost vegan diet" — but allows for occasional indulgences. "If I want cupcakes or a short stack, I don't deny myself," she's said. The actress offsets splurges with 15 to 20 minutes of daily cardio and Pilates. "I have to work out early because of my schedule," the 47-year-old explained. "The great thing about Pilates is that I can take out my annoyance from waking up early on the machines instead of human beings." Phew!

The brunette beauty has figured out a great way of keeping herself accountable — she enlists a workout buddy! "We'll go hiking one day and then we'll try a sculpting hot yoga class, then we'll do cardio," the Masked Singer panelist, 42, said of exercising with a friend. "It's hard to be invited sometimes, so we push each other." The songstress also sticks to a sensible diet: Breakfast is eggs with salmon or bacon, lunch is soup or sushi, and dinner is pasta or meat with veggies.

The newly engaged Emily in Paris actress is all about balance. She practices dance cardio with Body by Simone workouts and swims, though she's mindful of giving her body a break when it needs one. Dietwise, Collins, 31, eats clean but doesn't limit herself too much. "I love chicken, fish and vegetables and grains like quinoa," she said. "I steer clear of processed food and I'm very farm-to-table ... but I also treat myself to the occasional dessert when I'm out with friends."
