It's back on!
"Even though they are both busy, the relationship is solid," a source told People. "They see each other when they can."
The two first fanned reconciliation speculation when they were spotted on a sushi date on Dec. 30 in Los Angeles. But, according to the magazine's source, the couple has been back together for a while, saying Jen and Chris "are still dating and have been dating."
The couple split in October amid reports the J.Law wasn't comfortable with Chris' continued close relationship with his ex Gwyneth Paltrow, whom he shares two children with -- Apple, 10, and Moses, 8. Jen's worries have apparently subsided.
"She understands that the children come first with Chris and his relationship with Gwyneth is based around the family and it will always be a part of his life," the source said. "Things are good between them."
