Justin Bieber must be tearing his hair off.
Post-split Selena Gomez goes to town showing off what he's missing by wearing wide tooth-paste ad smile, cleavage-baring and body hugging dresses.
Since splitting with Bieber, 18, Selena have been upbeat and going places.
At the Vogue event in the designer's honor, an Gomez chatted with Chelsea Lately host Chelsea Handler, 37. The Spring Breakers star has yet to publicly comment on her split with Bieber.
The exes were first linked in November 2010 after a "cuddly" IHOP date, though they denied dating until the spring of 2011.
The Wizards of Waverly Place actress and the "As Long as You Love Me" singer called it quits in November 2012.
In the wake of their split, Bieber was photographed smoking what appears to be marijuana on Jan. 2, just one day after a paparazzo was killed chasing his Ferrari. (Bieber was not in the vehicle at the time.)
Selena definitely had some major trust issues with Justin and it's been a really challenging experience over the last year because of their crazy schedules.
By the looks of it, you would never guess that Selena just broke up with Justin because she looks so happy.

Justin has been sending Selena romantic texts, but she hasn’t responded. He wants her to listen to his new music, which was written for her, but she isn’t giving him an inch!
