CBS has officially announced the premier date for the 9th and final season of How I Met Your Mother as September 23rd 2013. In additional news (and as many of you have surmised or heard by now), Cristin Milioti will be added as a series regular for the 9th and final season!

Mark your calendars but remember I can only commit to one Premier party so send your best offer early 😉
