The magazine reported Sunday the word began getting out on Twitter when Faison's former "Scrubs" co-star, Zach Braff, sent out his congratulations.
Faison answered back Friday with a Twitter message reading, "If you like it then you better put a Ring on it."
There was no word on the details such as when or where the question was popped and whether a date had been set.
Faison, 37, has been married once before and has a son. Cobb, 33, co-starred with friend and former employer Jessica Simpson on "The Price of Beauty."
