Have Justin Bieber
and Selena Gomez
reconciled since their split in November
The former couple met briefly at her Los Angeles home on Wednesday, PEOPLE has learned. But what comes of the get-together remains to be seen.
Bieber, 19 is getting ready to head out on tour again, while Gomez, 20, has seemed quite happy to be single.
She even joked with David Letterman earlier this month that she had made Bieber cry
, and added: "I'm single. I'm so good."
A source told PEOPLE at the time that Gomez was truly moving on, and that she wanted Bieber to move on, too.
"She's becoming more and more comfortable with her decision [to split]," the source said. "But she doesn't like hearing the negative stuff. It saddens her. She wants the best for him. But every day she is more and more comfortable with her decision."
Meanwhile, Bieber has had a more turbulent time since parting ways with the Spring Breakers
In January, he admitted he was "pretty heartbroken"
and "not in the happiest place" following the split. Then, in early March, he suffered through a disastrous visit to London, which included a ruined birthday
, harsh criticism from fans
and an on-stage collapse
He later angrily denied rumors
that he was going to rehab and that his family was worried about him.
