Singer Jennifer Lopez posted a tweet Tuesday that included the hashtag “#AllLivesMatter,” but deleted it just moments later.

JLo’s social media missive included a photo of her and former “Hamilton” star Lin-Manuel Miranda’s recent performance on the Today show.

The post, however, caught the attention of several Twitter users who wasted no time in mocking the singer.

According to Seattle-based Black Lives Matter co-founder Marissa Jenae Johnson, the phrase “All Lives Matter” is a “racial slur.”

So the 46-year-old singer’s use of the phrase was met with scorn from social media users.

Seeing Jennifer Lopez tweet All Lives Matter is extremely disappointing. Guess she thought so too…..as the tweet was deleted. — Shane Avery (@ShaneAvery) July 12, 2016

Ugh. Now Jennifer Lopez is on that All Lives Matter foolishness, too? *sighs deeply* — (NKAYM-jee) 👧🏿 (@unicornrainbows) July 12, 2016

Jennifer Lopez deleted that tweet real quick. — Michael Arceneaux (@youngsinick) July 12, 2016

Lopez was using the tweet, at least momentarily, to promote her new collaboration with Miranda called “Love Make the World Go Round,” a tribute to the 50 people murdered during the Islamic terror attack on Pulse Night Club in Orlando, Florida.

Lopez and Miranda, along with Epic Records, plan to donate 100 percent of the proceeds from each U.S. download on iTunes, from July 8 to Oct. 5, to the Hispanic Federation for the Somos Orlando Fund.
