Heidi, Spencer “to Adopt an African Baby”

From being trapped in the jungle to sparring with Al Roker, Heidi Montag and Spencer Pratt have had quite a year.

Their goal for 2010?

"We're going to adopt an African baby, date Vince Vaughn, shave our heads, pretend Spencer is trapped in a balloon and have octuplets," they joke in a joint interview with Playboy.com while promoting their new book, How to Be Famous (out Nov. 16).

Asked why they wrote the book, "They always say, "Write what you know," and we know how to be famous," the two say.

In the book, they praise Us Weekly cover stars Brad Pitt and Angelina Jolie for being able to manipulate the press to their advantage.

They don't mean that in a bad way, either.

"Well, we wouldn't want to piss them off. She might steal Spencer—you know, because she steals people's husbands!" Montag says. "But seriously, we'd love to sit down and discuss fame with them. Consider this your formal invitation, Brangelina. Let's hang out sometime. We'll be SpeidiLina!"
