Huck Paisley will soon have a little brother or sister. Brad Paisley and wife Kimberly Williams-Paisley have announced they're expecting their second child in April.

"We're having so much fun with our little boy Huck, and we are thrilled that he will have a sibling," Kimberly tells PEOPLE. "He's going to be a great brother."

Brad and Kimberly were married in March of 2003. Their little boy was born in February of last year.

Kimberly is currently in Los Angeles filming her sitcom, 'According to Jim.' There's no word yet on whether or not the show will work her pregnancy into its storyline. Brad is set to co-host the CMA Awards November 12 with Carrie Underwood. He's up for four awards: Male Vocalist, Song, Music Video and Entertainer of the Year.
