Britney Spears indefinitely postponed her residency in Las Vegas due to her father's life-threatening health issues, the singer said in a statement on Friday.

"Britney: Domination" was scheduled to start in February and run through August at the new Park MGM resort, according to Rolling Stone. Spears announced that she was going on an "indefinite work hiatus," and it wasn't immediately clear when or if the show would be rescheduled.

Her father, Jamie Spears, was hospitalized several months ago and almost passed away, the singer said in a tweet. She said he has been recovering but "still has a long road ahead of him." Spears did not say why her father almost died.

In several tweets, Spears said she was heartbroken to postpone her residency but that spending time with her family was more important. "I hope you all can understand," she said.
