“Friends” star David Schwimmer is bracing for an international custody fight from hell! Newly split from wife Zoe Buckman, David fears his wife will take their daughter, Cleo, to live in England, sources told OK! Magazine. Now British-born Zoe, and all-American David are drawing battle lines, OK! Magazine has learned. “Zoe told David she’ll pack up and move back to England and take Cleo with her,” said an insider. “David’s not about to give up without one hell of a fight and said, ‘Not with my daughter.’ “Zoe’s a British citizen … all her friends and family are in the U.K. David understands that, and if she wants to go, fine, but she can leave Cleo with him.” While they’re yet to formalize the split and file for divorce, the couple is “staking out their ground,” said the insider.
