Jason Aldean is already hooking up with a hot blonde. Namely, actress Kristen Bell. The two have been named co-hosts of this year's CMT Music Awards. Nominations for country music's first fan-voted awards show come Monday, with the festivities airing June 5 on CMT and CMT.com. Both Aldean and Bell have been in the news in recent days. He announced his divorce, and thanks to a wildly successful Kickstarter campaign, Bell's cult hit Veronica Mars is being made into a movie. Shooting begins this summer.
