Sad news for the family of one of the members of Fifth Harmony. Lauren Jauregui's grandmother reportedly passed away.

It's unclear how the news officially broke -- the singer herself has not addressed the death yet -- but a little after 12PM ET today, @themikeinator tweeted, "Heaven gained an Angel last night.My mother-in-law passed away. Lauren's Grandma.Please keep us in your prayers & Lolo as well. #RIPAngelica."

Fans immediately responded by taking to Twitter to trend #RIPAngelica, #WeAreHereForYouLauren and #WeAreHereForYouFamilyJauregui. Of course, Harmonizers also offered up words of support to Lauren.

"Be strong, my love. It will hurt but will pass, you are not alone," @allyenar tweeted, while @jetaimecabeYo wrote, "I love you more than myself can not stand the idea of thinking that you are crying right now."

The tragic news is especially sad, given that this should be a joy-filled week for Lauren. Fifth Harmony released their new album, 'Reflection,' yesterday (Feb. 3). We'll continue to keep Lauren and her family in our thoughts during this tough time.
