Otto's publicist Jensen Sussman tells The Associated Press that they welcomed their first child, Ava Katherine Otto, into the world at 9:23 p.m. Tuesday at a Nashville-area hospital. She weighs 8 lbs., 2 oz. and is 19 ½ inches long.
Otto said in a statement: "She is beautiful like her Mama, and I am already wrapped around her tiny finger."
Otto has been opening for Toby Keith and Trace Adkins this summer, and he said he returned from a gig over the weekend just in time for the birth.
Otto scored his first No. 1 hit in 2008 with "Just Got Started Loving You." He also co-wrote last year's CMA song of the year, "In Color," sung by Jamey Johnson. Otto is releasing a new album Sept. 14.
