Pink reader Oga and I caught an interesting tweet (message) from Nicole Richie that she posted on her official Twitter profile last night (and is currently her most recent one) that gave all of her followers the head’s up that her “sister-in-law” Sarah Madden has joined Twitter and that everyone should follow her:

Sarah Madden is Joel Madden‘s little sister … so does this mean that Nicole and Joel are married (???) or does it mean that Nicole is just being a cheeky monkey by calling Sarah her sister-in-law just cuz she and Joel are together? I suppose it’s possible that Nic/Joel secretly got married but would Nicole really accidentally spill the beans on her Twitter account? HMMMM.
