Maya Rudolph, 41, is now a proud mother of four. The "Bridesmaids" actress has given birth to her fourth child, but not many people knew it. Confirmation about the arrival of the bundle of joy came after she was spotted at LAX with a baby.

According to E! News, the "Grown Ups 2" actress was seen at the Los Angeles International Airport on September 2 doting on a swaddled baby in a Bambino carrier. No other information including the gender of the baby is available at the moment.

In February, Rudolph was rumored expecting Baby No. 4 with her director husband Paul Thomas Anderson. It wasn't until two months later during an appearance on "The Ellen DeGeneres Show" that the "Saturday Night Live" alum confirmed her pregnancy.

When her "Gown Ups 2" co-star Salma Hayek reminded her of her vow not to add another child after the third, Rudolph said, "It's amazing how we forget. It's like that light pen thing they do in Men in Black. Somebody [pointed it in my face] and I was like, 'I don't know what you're talking about.' "

Rudolph and Anderson, 43, are already proud parents to two daughters Pearl, 7, & Lucille, 3, and son Jack, 2.
