Robert Pattinson visited one ridiculously lucky family of "Twilight" fans this week -- and it's all thanks to Oprah.
After the family sent O a letter saying they were all huge fans, the show agreed to set up an interview via Skype for next week's "Eclipse" episode -- but when it came time for the online interview, they heard a knock on the door ... with R-Patz waiting on the other side!
Mama Maria tells Twi-blog Pattinson Ladies the fam started "Screaming like a bunch of maniacs. He was great. So nice. Funny. And sooo tall. You was beautiful."
The family was then given tickets to the taping of the "Twilight" ep of Oprah -- which airs next week.
