I don't know who writes better Instagram captions and comments about their love, Travis and Kourtney or Megan Fox and Machine Gun Kelly. They are still gushing over the beginning of this new chapter in their lives and it's so cute. Travis Barker's ex, Shanna Moakler is not taking the love so well. She took down all the pics of her kids from her Instagram because of their support for this new addition to their family.
