Sarah Michelle Gellar held her daughter Charlotte's hand as they ran errands in Santa Monica yesterday. Sarah's maternity style was on display as she covered up her pregnant stomach in a fitted jacket. She's expecting her second child with husband Freddie Prinze Jr. later this year, and the soon-to-be dad of two will be the center of attention with Father's Day on Sunday — we're taking a look at 100 celebrity dads to mark the occasion. SMG will be in the spotlight first though, since she's being honored with a leadership award at the LA Zoo's annual Beastly Ball tomorrow. Sarah's also featured in our PopSugar 100, so make sure to place your votes before the contest ends on Sunday.
