Oh no, he didn't!

Late night talk show host and comedian George Lopez had a full-on laugh-out-loud satirical "world exclusive interview" with Arnold Schwarzenegger's former housekeeper -- better known as his baby mama, Mildred Patty Baena -- on his show Monday night.

Lopez dressed up as a woman, with a blonde wig and full makeup, strangely resembles Baena! The interviewed was set up "via satellite" from her home in Bakersfield.

The host asks "Patty" how the news of their lovechild got out. The housekeeper claims people "started to talk" as word got out "there was a 10-year-old who could bench press 450 lbs. -- and was very gropey."

The comedian jokes, "Like father, like illegitimate son." Touche!
