Are Sienna Miller and Rhys Ifans finally ready to drop the "Who, us? We’re just friends" party line and take their relationship public? Just two weeks after the pair engaged in a midair makeout session aboard a flight from L.A. to London, Sienna and Rhys were spotted canoodling aboard a yacht in Los Cabos, Mexico, this week. The couple (shown above in mid-canoodle) took a dip in the Sea of Cortez and later ran into a pod of whales during their romantic day on the high seas.
"Sienna has spoken of wanting to spend the rest of her life with him," a source says in the current issue of Us Weekly. "He's always making her laugh."
With friends like these, who needs a lover?
