6. Tom Arnold & Dax Shepard
There are close friends then there are close friends. When Arnold and his wife were experiencing infertility issues, Shepard offered his own sperm to the couple. Not sure if that’s friendship or just plain creepy.

7. Lea Michelle & Kate Hudson
Okay, maybe this one is not odd per se. Michelle credits Hudson with helping her recover from the death of boyfriend Cory Montieth. Hudson opened her house to Michelle when reporters threatened to overwhelm Michelle and her family as she sought privacy. That’s friendship.

8. Rihanna & Jennifer Lawrence
They bumped into each other in Paris and appeared together in Instagram photos.  Not sure if this falls into the category of celebrity friendships or just two famous people being polite and doing a little publicity work. Either way, it’s pretty hot.
