Andy named his son after his grandfather.

Nearly two weeks ago, Cohen was surrounded by the “Real Housewives” cast and close pal John Mayer as he celebrated his baby shower in Beverly Hills. Andy also traveled to the East Coast for another baby shower, this one with Sarah Jessica Parker and Kelly Ripa.

In December, Cohen announced he was expecting his first child via surrogate. At the time, he shared on his show, “Tonight, I want you to be the first to know that after many years of careful deliberation, a fair amount of prayers and the benefit of science — if all goes according to plan, in about six weeks time I'm going to become a father.”

After hearing about his baby's arrival, Bethenny Frankel and many other members of the "Real Housewives" cast congratulated Andy on social media. See the reactions below!
