Grammer tells People.com, ""Kayte's the most wonderful person in the world. I'm just so happy! We're really excited.
""I've always wanted shot-gun wedding pictures so we can show the kids later on! We wanted to celebrate and re-dedicate (ourselves) to how much we love each other and to our growing family around the bend... I love that she had the courage to marry me twice!""
Walsh is due to give birth to twins next month (Jul12). The babies will be Grammer's fifth and sixth kids.
