Britney Spears has canceled her new Las Vegas residency and will be on an indefinite work hiatus "to devote all of her time to her family and their efforts to care for her father during his recovery," the pop star announced Friday.

"I don't even know where to start with this, because this is so tough for me to say," Spears wrote on Twitter, sharing an old photo of herself with her parents when she was a child. "I will not be performing my new show Domination. I've been looking forward to this show and seeing all of you this year, so doing this breaks my heart."

"However, it's important to always put your family first… and that's the decision I had to make," Spears continued in a second tweet. "A couple of months ago, my father was hospitalized and almost died. We're all so grateful that he came out of it alive, but he still has a long road ahead of him."
