Mother's Day comes just one week after the makeup mogul flew to Miami to celebrate Scott's 29th birthday.
A source told PEOPLE that Jenner and Scott, 29, had dinner with a group of friends at Komodo before heading club LIV, where Scott performed. "They were very close and affectionate," the source said of the pair — who split in 2019 — adding that they are "not fully back together,"
"Even after they split, they always spent a lot of time together," said the source. "They are great co-parents and love hanging out. They share a fun life with Stormi, but have separate homes. They haven't dated anyone else seriously since they split though. It always seemed possible that they would get back together."
