Britney Spears is throwing her support behind Janet Jackson.

The “Toxic” songstress, 42, posted — and quickly deleted — a sweet message about the “Scream” hitmaker, 57.

“Thank you to this beautiful lady for keeping my dreams and heart alive,” Spears wrote on Instagram Sunday.

“She’s always been the deepest and brightest woman at the same time. She went through so much but I feel she is someone I will look up to for the rest of my life,” the “Circus” singer went on.

“Thank you for your music and your divine way of untangling intelligence to a far more clear view than anyone could ever imagine.”

The sweet caption, which was accompanied by a photo of Jackson’s cover art for her 1993 album, “Janet,” seemed to reference the controversy surrounding her Super Bowl XXXVIII performance with Justin Timberlake.

Spears’ message comes amid her ongoing feud with her ex-boyfriend, who infamously exposed the five-time Grammy winner’s chest in the middle of the 2004 Halftime Show.

While Jackson and Timberlake, 43, both issued public apologies at the time, the “Sexyback” chart-topper’s career remained largely unscathed amid the fallout.

The tide has turned in recent years, however, and Timberlake fell out of favor in the court of public opinion during the Free Britney movement.

Most recently, Spears revealed in her memoir, “The Woman in Me,” that she had an abortion while dating Timberlake in the early 2000s because he “wasn’t happy” about the pregnancy and “didn’t want to be a father.”
