Jennifer Lopez is canceling her tour to spend more time with her family, and is “heartsick” over the decision to pull the plug, the singer announced Friday.

Sources said Lopez, 54, was canceling the tour due to a sensitive time in her personal life, as she and husband Ben Affleck are said to be headed toward a split.

We hear that Lopez was sending a special message to her fans via her “On the JLo” newsletter Friday, telling them of canceling the tour, “I am completely heartsick and devastated about letting you down.”

She also said, “Please know that I wouldn’t do this if I didn’t feel that it was absolutely necessary.”

“I promise I will make it up to you and we will all be together again. I love you all so much. Until next time…”

Representatives for Live Nation announced that the summer tour, “This Is Me… Live,” was canceled, saying in a statement, “Jennifer is taking time off to be with her children, family and close friends.”

Sources insisted that pulling the plug was not due to poor ticket sales, but rather for personal reasons and wanting to be with her kids.

The US tour was rebranded in April, after it had initially been called “This Is Me…Now” after Lopez’s latest album, in which she sang about her journey to a rekindled love with Affleck.

The star’s ninth studio album made a debut on the Billboard 200 at No. 38.

But sources said there had been a recent uptick in concert sales, and that some markets were performing well including sales in cities such as Newark, which had 92% of seats sold, and Toronto, with 86% of seats, plus markets like Orlando, Miami, Rosemont and Anaheim.

Lopez was spotted earlier this month in good spirits headed to rehearsals for the shows, as rumors of a split with Affleck swirled.

Lopez has 16-year-old twins, Max and Emme, with her ex, Marc Anthony.

A source told Page Six that Lopez and Affleck are going to end their marriage after being unable to make things work. The duo first sparked speculation that their relationship was on the rocks when Affleck did not attend the Met Gala with Lopez earlier this month.
