Felicia Fields, a longtime friend of the Hudson, confirmed to the paper that the event happened on Saturday.
“It was a baby shower, a quiet gathering of friends and mostly family,” Fields, also a singer and actress, said of a gathering in a relative’s home. “They’re really trying to keep it kind of quiet.”
She added: “It was a nice time that we had.”
When asked if Hudson received blue or pink gifts, Fields said, “They don’t know [the gender]. More yellow.”
Another paper, the Chicago Sun-Times, reports Hudson is seven months along.
A rep for Hudson had no comment.
Hudson, 27, who is engaged to Harvard-educated-lawyer-turned-wrestler David Otunga, has also kept mum about her upcoming wedding date.
