Selena Gomez wore a navy, long-sleeved jumpsuit at the American Airlines Center for KISS FM's Jingle Ball in Dallas on Monday, leaving many fans wondering if she's been trying out new fashion styles since her break up with Justin Bieber.

"The 21-year-old looked cool and confident while she rocked the plunging ensemble, despite the fact that the neckline was practically down to her navel!" HollywoodLife.com writes.

"The star is a major fan of the jumpsuit trend so it comes as no surprise to see her in this outfit. Even though the plunging neckline showed off a lot of skin, it was balanced out by the wide-leg pants and the longer sleeves."

Selena Gomez and Justin Bieber's break up may have changed his love life forever - the teen heartthrob released his "Change Me" track on Monday, revealing how much his past relationship affected him.

In this soulful piano ballad, he really pours his heart out, singing, "Maybe you could be the light that opens up my eyes," HollywoodLife.com also writes.

Justin Bieber was spotted making out with a model on his motorbike in a 12-second teaser of his "All That Matters" video, leaving man fans wondering if it left Selena Gomez jealous.

"The teaser starts in a dingy room where Beibs is sitting on a motorbike and a woman slowly bends toward him to kiss him. The shot is set in a low light to give a romantic feel to the song. In the second shot Beiber is seen singing 'What's a king bed without a queen' in front of the camera," the International Business Times writes.
