Fifth Harmony member Dinah Jane is celebrating a big birthday today and she's getting lots of love from celebs and her besties on social media. Of course, we can't wait to see if she'll throw a super fun bash for the occasion or lay low.

Regardless, we thought it would be fun to take a trip down memory lane and look back at Dinah through the years. Beginning with her outstanding and jaw-dropping performance on the X-Factor to her most recent gig with 5H!

She sure has come along way in the past four years and we can't wait to see what is in store for the future!
