Taylor Swift has denied reports that she has undergone breast augmentation surgery. The rumors were sparked after a photo of her in a tight dress suggested that she was surgery. Around the same time, she was also photographed shopping for Lingerie in Los Angeles - which suggested that she is shopping for her newer and bigger bust. As rumors swirled online, even experts stepped in to offer their opinion.

Plastic surgeon Dr. Anthony Youn told Hollywood Life: "The country star appears to be following in the footsteps of another female country singer, Dolly Parton, and enhanced her breasts."

Meanwhile, Taylor Swift and Dianna Agron got together with their girlfriends this week to celebrate Oscar winner Shirley MacLaine's 78th birthday. They dressed up for the occasion and posed for fun pictures in MacLaine's honor. The four girlfriends dressed up in vintage gowns, flower hats and gloves and went out for a meal at Beverly Hotel's Polo Lounge.
