How does diazomethane react with a diketone?

Homework Statement

What are the products when 1-phenylbuta-1,3-dione reacts with diazomethane in
presence of ether?

Homework Equations

The Attempt at a Solution

I tried to do it this way:
Since carbonyl carbons of 1-phenylbuta-1,3-dione , one of them might get attacked by the positively charged nitrogen of diazomethane ;and the oxygen ,will therefore (maybe?), bond with the other nitrogen . And then I think the ether will do something but the problem is I can't reason out what happens next or is this approach even correct or not.
Is this some named reaction ? I tried to google it and stumbled upon the Nierenstein reaction but that is not exactly this reaction , right?
Any hint or help will be REALLY appreciated.
Thanks in advance.
