Nick Jonas is single and ready to mingle. On occasion, he has been seen gushing about his rumored girlfriend/hookup companion Kate Hudson. Monday, he made it clear that he is very much unattached to any girl at the moment in a series of tweets. "I've now been romantically linked to two of my friends wife and girlfriend while third wheeling at dinner with them, #sofunnyiforgottolaugh" Jonas said. "I've been very open about the fact that I am not in a relationship with anyone right now. I am pretty sure I am the most reliable source."
