Her famous alter ego, Miranda Sings, took a different approach. "THE BABY RIPPED MY ENTIRE TOOKIE! FREAKIN BRAT," she wrote.

Grande responded on Monday with "OMG," when the YouTube star announced she was going into labor.

Ballinger appeared in the "Mean Girls" and "Bring It On" scenes during the music video, and was featured with heavily pregnant.

Ballinger seemed to get very close to Grande during filming, even showing off her bump next to the singer in a belly baring cheerleading outfit.

She revealed the baby boy looks exactly like his daddy and she's "so in love with him!"

At least Auntie Ari still has time to get baby his first Christmas present!
