Kelsey Grammer may be embroiled in an ugly divorce battle with wife Camille Donatacci, but he hasn't let it affect his kids.

The La Cage Aux Folles star told David Letterman that his son's biggest struggle hasn't been with family issues, but rather learning how to read. Grammer also announced that he would marry fiancee Kayte Walsh, who is pregnant with his child, in February.

Donatacci, who currently stars on Real Housewives of Beverly Hills, filed for divorce in June amid reports of Grammer's infidelity. He announced his engagement to Walsh in December. It is unclear whether his divorce will be finalized in time for a February wedding. —ISHITA SINGH
