Carey Mulligan has happily moved on from her “Wall Street: Money Never Sleeps” co-star, Shia LaBeouf. Mulligan has been spotted out and about in town with British actor Eddie Redmayne. A spy reports, “They look really happy together.” Redmayne won a 2010 Tony Award for his performance in “Red” and will soon be seen in “My Week With Marilyn” with Michelle Williams, in which he plays an assistant on the British set of “The Prince and the Showgirl” who persuades Marilyn Monroe to escape for a week into British life.
