Remember when Allan Wu and Wong Lilin’s daughter, Sage, turned 16 last year? At that time, all we could think of was — how did time fly by so quickly?

Well, now it’s time to celebrate Jonas' birthday as the teen turned 15 on February 21.

Allan — he and Lilin split up in 2013 after nine years of marriage — celebrated the special occasion by bringing Jonas and Sage out for a celebratory meal at mezza9, the same restaurant they dined at back in September for Sage's birthday.

No points for guessing what’s their favourite restaurant now. 

"Some Little Man who isn’t so little anymore turns fifteen today! 

Happy Birthday to you, Jonas! There isn’t much I need to say cuz you already know nothing brings me more pride and joy than watching you grow up—and watching you now start to really grow! 

So keep learning, trying new things, and challenging yourself because you know I’ll be there for you every step of the way! Love, Dad” Allan wrote in his caption, adding in some pictures of the three of them.
