AceShowbiz - Charlie Puth has finally introduced his new girlfriend to the world. The "We Don't Talk Anymore" singer made his relationship with Brooke Sansone Instagram official as he celebrated his 31st birthday.

On Friday, December 2, the musician shared black-and-white photo booth pictures of him and his girlfriend smiling and playfully kissing. He captioned it, "Ohhhhh I'm NOT a loser…'cause I didn't lose her!!! (Happy birthday to me.)"

Charlie confirmed he's no longer single when appearing on "The Howard Stern Show" on October 18. Noting that he's "in love" with a girl he has known since childhood, the crooner said it is "really nice" to have someone from his early life by his side as his fame escalates.

"Yeah. Definitely. I think this is it," the New Jersey native said when asked if he was in love. "As my life gets more and more turbulent and I travel everywhere, it's really nice to have someone close to me that I've known for a very long time."

"She's someone that I grew up with. I knew her from a small town in New Jersey," he further elaborated. "She's always been very, very nice to me and I assume that when times are inevitably hard in the future, she will be there for me, because what is life without valleys and peaks."

The "Left and Right" hitmaker went on to note that if he were ever to propose to his girlfriend, he would "go out of his way" to make sure the media remain unaware because the attention could become "too much." He continued, "Honestly, I get so scared of people now, like I can't really walk anywhere for whatever reason, and I think the more that happens the more I just want to retreat to someone that I've known for a long time."
