Though Mark-Paul Gosselaar recently separated from Lisa Ann Russell, 38, his wife of 14 years, he isn’t letting it affect his job as a devoted dad to his son Michael, 6, and daughter Ava, 4. Mark-Paul makes being dad his No. 1 priority and he’s making a point to mark every milestone and make sure his kids don’t miss out on anything — including visits from the tooth fairy! Mark-Paul exclusively told In Touch at the EMA Awards in Los Angeles, “The kids’ teeth are flying out and I am busy being the tooth fairy!” But Mark-Paul, 36, isn’t letting the tooth fairy spoil his kids, telling In Touch, “The tooth fairy gives them quarters for every tooth they’ve lost. We’re up to three, so that’s 75 cents.” Mark-Paul tells In Touch that he hasn’t made a playdate with his old Bayside High classmates Mario Lopez and Tiffani Thiessen, but hopefully a class reunion soon will be in the works!
