Ellen Pompeo carried baby Stella on her hip leaving their NYC hotel on Thursday. It's been a little over a month since the pair was spotted on their first public adventure and now they're exploring the East Coast. Ellen's trip to the Big Apple is on behalf of the American Cancer Society and as their celebrity ambassador she was on hand earlier this week to launch their new campaign, Choose You. While she's prepping for her first Mother's Day with Stella her Grey's Anatomy costar Eric Dane is visiting Paris with his favorite ladies, Rebecca Gayheart and sweet little cover girl Billie. Both Eric and Ellen are still caught up in all the onscreen Grey's Anatomy drama, but Pompeo says she may only stick around the show for a few more years since she says she's not sure "how much more Meredith Grey the world wants."
