Washington, November 14 American singer Heidi Montag and her husband Spencer Pratt have spill the beans on their plans for 2010.

The couple joked about their list for next year while promoting their new book, How to Be Famous.

"We're going to adopt an African baby, date Vince Vaughn, shave our heads, pretend Spencer is trapped in a balloon and have octuplets," Us magazine quoted them as saying in a joint interview with Playboy.com.

The duo also took a dig at Brad Pitt and Angelina Jolie in the book over their apparent manipulation of the press, adding they mean no harm.

Montag said: "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!" (ANI)
