No, you should not. If you had kids, I would say to wait about an hour, and respond with something like "Sorry, I've been real busy and just saw this. What's up, are the kids okay?" or something, but since you DON'T, there's absolutely no reason to respond to this, at least not now.
WAIT FOR GUCCI.
