The Fifth Harmony ladies are big fans of other musical acts.

Watch The Ladies Of Fifth Harmony Perform On 'The Today Show'!

Since coming off The X Factor this girl group has mastered doing some incredible covers of artists they admire, including Taylor Swift, whom Camila Cabello has become pretty close friends with.

Cabello finally got to see her Swift live in concert Friday night when the blonde's 1989 World Tour rolled into New Jersey.

Cabello went with her younger sister and it seems like her mom went too or at least gave Cabello advice on how to "be at least a little cool," to see Swift's gig in East Rutherford at MetLife Stadium.

It was a big night for the tour as Haim joined as an opener.

Swift had The Weeknd join her on stage for a duet of "Can't Feel My Face" and the United States women's national team that just won the World Cup took to the stage too.

Some of Swift's other pals hit the stage too, including Hailee Steinfeld.

Anyway, Cabello sang at the top of her lungs and danced around with her sister as they enjoyed the show.

"[I] cried and danced and laughed and sang," Cabello tweeted well after the gig ended.

She even put "13" on each of her hands like Swift used to do.

"I FELT ALL THE FEELS," the 18-year-old added.

Cabello shared an Instagram video from the concert too. She sang along to "Wildest Dreams" and in the caption dished that Swift is her "musical queen."

ok so i have always wanted to go to a @taylorswift show and write 13 all over my body and if my mom hadn't told me to calm down and be "at least a little cool" i DEFINITELY would've been dressed up as a starbucks lover. tonight i sang at the top of my lungs to all the Taylor songs that have been the soundtrack to my life- that have understood how I felt more than anybody else did. my sister and i danced like maniacs and i screamed I LOVE YOU!!! when it got quiet and didn't really care who was looking BAHAHA. for anyone that has known me from the beginning you know she is my musical queen- so for that reason- and just me coming to see one of my most magical friends absolutely kill it- TONIGHT. WAS. AWESOME. it's 4 am and im exhausted and happy. LOOK AT THAT CROWD. LOOK AT THEM SINGING. LOOK AT IT A video posted by camila_cabello (@camila_cabello) on Jul 11, 2015 at 1:54am PDT
