Talk about cool kids! We can't think of a cooler BFF combination than Ally Brooke from Fifth Harmony and Sydney Sierota from Echosmith. And guess what? It seems like Ally can't either!
"MY SYDNEYYYY you are such a sweet friend to me," the 5H singer wrote on Instagram. "So blessed to have you in my life... ily."
AWW! Doesn't it sound like these gals are really good friends? We're so glad that they have each other! <3
