Mark-Paul Gosselaar and estranged wife Lisa Ann Russell are ending their marriage, but they agree on one important matter: custody of the children.
Gosselaar, 37, who cited irreconcilable differences when he filed for divorce
in June, requested joint custody of Michael Charles, 7, and Ava Lorenn, who turns 5 on Saturday.
According to court documents filed April 1, Russell is seeking the same thing. Russell, who had been married to Gosselaar for almost 14 years, is also seeking spousal support.
