“Dancing With the Stars” beauty Stacy Keibler has split with actor Geoff Stults. A source told us, “It’s over and done, and they both have moved on.” Stults, star of “She’s Out of My League,” was spotted at Soho House in LA last week looking “dapper, on the prowl and flirting with women including ‘Plain Jane’ host Louise Roe and Bonnie Somerville,” a source said. “He and Stacy talked last year about getting engaged, but they’ve been partying separately for several months. Geoff is often out with his [actor] pal Bryan Greenberg living the single life.” Their reps didn’t get back to us.
