Despite ongoing marital woes, George Lopez claims that pal Sandra Bullock "could not be happier."

Lopez spoke to PEOPLE yesterday about Bullock's newly adopted son, Louis Bardo Bullock, saying, "I am a proud uncle and [my wife] Ann is a proud aunt. Sandra is a loving, giving person, and Louis could not be in a better home and she could not be happier."

Meanwhile, Lopez told Extra that he had known about the adoption for a few months.

"I love that she was able to do it privately and really take care of Louis, which is first and foremost," he said.
