My secret santa won't be receiving his gift until January!

My client owes me a few grand and I was expecting that this month. Didn't happen. (Edit here: he's not at fault, he had a bit of an emergency and I don't fault him for being late paying me, I know he'll never read this but I don't want to insinuate he's a bad guy) So I'm flat broke, absolutely and completely, until he catches up in early January. I have an excellent plan for my santee's gift, he gave me a lot of great ideas on his bio, but I won't be able to execute this until January and I feel terrible. Should I contact him and tell him directly, or would that violate the point of 'secret' santa?

Edit: Also, MY santa did an awesome job with my gift, and I was really happy. I've hesitated posting the results due to my embarrassment in being delayed getting my gift out to my santee (I don't like to receive when I haven't given) so his credit and appreciation is coming soon...

Edit 2: I just now saw where I can pick up the slack for someone who didn't follow through. To help make up for my lateness, I'm signing up to gift to an additional person. That'll help alleviate a little of my guilt, and make someone smile when they randomly receive a Christmas gift in January :D
