George Strait has learned that his son Bubba and wife Tamara will soon be the proud parents of a baby boy. That means the King's first grandchild -- who was announced last month -- will be the new grand-prince of country music when Tamara delivers next February. The couple were married last December.

Country Weekly first broke this detail. Previously we reported that Bubba Strait's birth name is George Strait Jr., meaning the newbie could be the third in a line of music royalty. Bubba Strait has recently become a big part of his father's success, having helped co-write seven songs from George Strait's new 'Here for the Good Time' album.

In addition to an album of originals due in stores this week, Strait will have another greatest hits release in stores on Tuesday. ‘George Strait – Icon' will feature 11 songs, including nine No. 1 hits and two fan favorites. ‘Give it Away,’ ‘I Cross My Heart,’ and ‘Amarillo by Morning’ are a few of the songs on the greatest hits collection.
