She's livin' her best life these days!

Ariana Grande celebrated her 25th birthday with a blowout bash at a private karaoke bar inside the bowling alley Frames in NYC, and her friends and family shared some inside videos with us on social media. There were cupcakes with the songstress' childhood photos on them, there was lots of dancing, and we bet there were more than a few make outs between her and fiance Pete Davidson!

The smitten couple treated guests to a duet of Evanescence’s 2003 hit “Bring Me to Life,” and the songstress also performed Beyonce's "Love On Top," Page Six reports.

Her SNL beau gushed over her on Instagram earlier in the day, and he's one smitten kitten!

"Happy birthday to the most precious angel on earth! you’re my favorite person that ever existed 🙂 i love you sm,” he captioned a photo of the pair. He wasn't done, though!

"One more for the queen. Words can’t express what a real f*cking treasure this one is," he wrote on another.

They've had a real whirlwind romance to say the least! They began dating in May and got engaged after less than a month, and recently moved in together in NYC. Before that, they both were in long term relationships, he with Larry David's daughter Cazzie and she with rapper Mac Miller.

Where was our invite?
