Eric Dane rolled up his jeans to hit the sandbox with Billie in Beverly Hills on Sunday. It was the second park day in a row for the 1-year-old after she had a play date with mom Rebecca Gayheart on Saturday. Rebecca, who is pregnant with the couple's second child, was later spotted grabbing lunch at Joan's on Third. Eric seems to be all about spending quality time with his daughter after returning home from a stint in rehab, and the duo had a similarly smiley outing earlier this month. Eric is not only back to his family, but he's also getting to work on Grey's Anatomy. A new promo for Grey's Anatomy was released last week, and though the eighth season doesn't air for about a month, the teaser does reveal a few spoilers. Eric's costar Kevin McKidd also shared details about the show at Disney's D23 Expo this weekend, saying things are going to be rocky for his character Owen and onscreen wife Cristina.
