Less than a month after saying she is the happiest she has been in a while, Selena Gomez was spotted hanging out with Justin Bieber on Thursday. The 21-year-old singer/actress broke up with Bieber, 19, last January, after Bieber was accused of cheating on the “Spring Breakers” star.

Afterwards, she even teased Bieber on the “Late Show with David Letterman.”

"Last time you were here, you were with Justin Bieber," Letterman said to her on an episode that aired in March. "That's not going on now."

"No, I'm single," Gomez responded. “I'm so good.” “Now, the last time he was on,” Letterman said, “he and I got into a conversation and he said something and I said something, and then he said something and I said something, and I made him cry.”

As the audience laughed, Gomez retorted, "Well then, that makes two of us."

Following the breakup, Bieber seemed to have acted up, showing up very late to his concerts and publicly smoking marijuana, amongst other inappropriate actions. So maybe having Gomez back in his life is just what he needs for the New Year.

Just a few weeks ago, Bieber said during a radio interview that he and Gomez were “not talking.” “[The break up] affected us, especially when we are in front of so many people. It’s such a public thing,” he explained. "It’s just hard for the both of us. But you know, she’s a great woman. I love her 'til this day." But evidently things have changed recently regarding the two not talking. Gomez was spotted riding Segways with him near his Calabasas, Calif., home.

Do you think the two are dating again, or simply working on remaining friends?
