Heidi Montag and Spencer Pratt: “We’ll Be SpeidiLina!”

Following in former co-star Lauren Conrad’s footsteps, Heidi Montag and Spencer Pratt are trying their luck in the book market.

The MTV co-star couple are currently promoting their literary work, How to Be Famous, recently explaining of the decision, “They always say, ‘Write what you know,’ and we know how to be famous.”

While promoting the book, due out on November 16th, Heidi and Spencer joked with Playboy of their 2010 plans, “We’re going to adopt an African baby, date Vince Vaughn, shave our heads, pretend Spencer is trapped in a balloon and have octuplets.”

The “Hills” lovers also chatted about Brad Pitt and Angelina Jolie’s well-plotted press power, as Heidi told, “Well, we wouldn’t want to piss them off. She might steal Spencer—you know, because she steals people’s husbands! 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!”
