Jennifer Aniston left little to the imagination when she stepped out in New York City on Thursday, June 23. The "Friends" alum turned heads as she flashed her nipples in a tight white tank top while walking down the streets of the Big Apple.

The 47-year-old actress flaunted her enviable curves while out and about in the city following pregnancy rumors, which were later denied by her rep. The "We're the Millers" actress teamed her sexy tank top with a pair of green army trousers, a leather belt and strappy wedges. Sporting gold sunglasses, Jen kept her head down while making her way into a building.

On the previous day, Jen was photographed heading into the same building while showing off her slim figure in a pair of black leggings and a black tank top. She also carried a denim jacket under one arm, keeping her belly partially covered.

Jen previously revealed that being beautiful and fit was not hard. Her secret to beauty inside and out is water and plenty of sleep. "I always try to sleep for at least eight hours a night and, of course, water, water, water! I drink 100 ounces of Smartwater every day," she told Shape magazine. "But occasionally I just have to have a Diet Coke - there's nothing like it."
