The star celebrated the milestone with a big ol' birthday bash surrounded by friends, Polaroids and best of all, cake(s)!
Sel took to IG to share pics from the occasion and srsly, WHY weren't we invited!?
"Happy birthday Sel!" she captioned one pic.
"Thank you for all of my bday love," she captioned another. "I couldn't be more blessed. A lot of you don't realise how much you mean to me. I. Love. You. Think 25 is going to be epic. xo."
HAPPY BIRTHDAY QWEEN!
