Justin Bieber stopped by his ex-girlfriend Selena Gomez's house on Wednesday night right before heading back to Europe.

The 19-year-old Canadian singer reportedly arrived with his security in a large black van around 3:30 p.m. and stayed at Gomez's home in Encino, California for an hour.

Shortly after Bieber left, the "Spring Breakers" star was seen driving away from the house.

While some fans were hoping that the two young celeb are attempting to rekindle their romance, a source close to the actress told omg! that that's not the case. "Definitely not," said the insider. "She is not getting back together with him."

"She's really happy right now, surrounding herself around good friends," continues omg!'s source. "She's been working a lot and is excited for everyone to hear her album ... including Justin."

The former Disney star recently acknowledged her break up with Bieber in public for the first time during her appearance on "The Late Show" admitting that she made her famous ex-boyfriend cry.

The conversation started when Letterman asked Gomez if she has dated anyone else since she and Bieber split in January.

"Do you date? Do you go out and see -- seeing boys now?" Letterman asked. "No, not yet, no," responded the 20-year-old entertainer.

Letterman went on to say, "Now, I remember last time you were here, you were with a Justin Bieber?"

"I was with a Justin Bieber?'" she retorted, laughing and adding that she is "so good" with being single.

"Good, yeah. I think you're fine," Letterman as the audience applauded.

"Now, the last time he was on, uh, he and I got into a conversation, and I -- he said something and then I said something, and then he said something and I said something, and I made him cry."

"Well, then that makes two of us," she said smugly, and then pounding Letterman with a fist bump.
