Former couple Allan Wu and Wong Lilin’s daughter, Sage, just celebrated her sweet 16 on September 30. Yup, you read that right. Don't kids grow up so fast?

 Both Allan and Lilin dedicated posts to Sage on her special day, posting photos with the birthday girl that appear to have been taken during their own celebratory dinners.

"At the cusp of so many discoveries! Be gentle with yourself and the world. Happy sweet 16 beautiful S (sic)” wrote Lilin, who celebrated her 48th birthday just a month prior.

 Meanwhile, Allan, also 48, headed out for dinner at mezza9 with Sage and Jonas, his 14-year-old son with Lilin.

"Sweet 16! Happy Birthday, Sage Wu! It still feels like yesterday when I beamed with love as I cradled your tiny self like a football sixteen years ago. So much has changed and time has indeed flown by faster than I could’ve imagined, but there has been nothing that has brought me as much joy and pride as watching you become a kind, generous, and hard-working young lady. I wish you nothing but the best and hope one day you can experience the same boundless happiness I’ve had in being your father. Love, Dad” wrote Allan.

And as a very detail-oriented netizen pointed out in the comments section, it looks like Allan had gifted Sage a brand-new iPhone as a birthday present. Not bad at all.
