The renewed romance between Jude Law and Sienna Miller seems to be going just fine, according to Page Six, as the actress has reportedly invited Law to jet off to Barbados with her to celebrate her birthday today and his tomorrow. “Jude is keen to spend some of the holidays with his kids, but it’s a tempting offer,” a source says. “Sienna has always maintained she and Jude are soul mates despite their past troubles.”
