Nick Lachey  and Vanessa Minnillo  held hands leaving lunch in Beverly Hills yesterday. Vanessa's been keeping busy during her pregnancy while also filming upcoming episodes of her prime-time game show, Wipeout. Meanwhile Nick is fully engrossed in the baseball season and supporting the Reds. Nick visited Cleveland over the weekend and led his hometown crowd in singing "Take Me Out to the Ballgame." Baseball's not the only thing on Nick's mind however, he's also reading up on becoming a first-time dad. Nick just finished Dad's Pregnant Too, a guide for expecting dads-to-be, which he called a "great read" for guys prepping for fatherhood.
