But just because she's "doing well," that doesn't mean she's happy how things have turned out.
"She's sad," a source tells me. "It's hard for her."
Gomez has been in NYC since promoting her new fashion line for Kmart as well as being honored last night by Glamour magazine."It's really good that she's with family and friends," the source said.
Gomez will be in her native Texas tomorrow with Ryan Seacrest to help him open a broadcast studio for patients at Children's Medical Center in Dallas.
And then she'll be back to focusing on her next album. "She's going to be in the studio," the source said. "That's what she's focused on."
Her next movie, the very risqué Spring Breakers with James Franco, Vanessa Hudgens and Ashley Benson, is set to be released sometime in the spring while Getaway with Ethan Hawke will hit theaters in August.
Meanwhile, Bieber was spotted having a fun night with friends in NYC on Sunday, dining with a large group at the Upper East Side's Philippe.
A source at the restaurant tells E! News that "he was having a good time with his friends, they were enjoying the food, and left after the [Jets] game was over."
Bieber is also continuing his world tour that is already booked through next April.
And the big question remains: will J.B. and Gomez get back together?
"Of course, no one knows," the source said. "They're young and in love, so you never know."
